David,
Yes, it does require U3 compatible software that will work on the drive.  I
know Jaws won't be able to be run from the thumb drive, but was wondering if
the applications installed on the thumb drive would be able to be read with
Jaws.
This is an old article, but here is more information about the U3 thumb
drive.
 
 
Applications Launch from USB Drives
 
U3 and partners add smarts to thumb drives, so users can carry desktops in
their pockets.
 
Technology startup U3 is expected to announce Monday the release of USB
drives based on its smart computing platform, which lets applications run
directly
 
off USB drives, independent of other storage devices. 
 
Smart USB drives based on U3's software and hardware platform will allow
users to carry their entire PC in a USB drive, so that when they hook up to
a PC
 
on the road, it will have the same look and feel as their work or home PC. 
 
Vendors Ready
 
USB smart drives are expected to be announced by hardware vendors including
SanDisk and Verbatim at Demofall, occurring this week in Huntington Beach,
California.
 
Several software vendors, including America Online and the Mozilla
Foundation, are expected to announce products that run directly off the USB
smart drives. 
 
"U3's concept is about taking your whole personal workspace with you, not
just the data, but the files, folders, preferences, plug-ins, settings,
everything
 
you need, to make any PC feel and look and act like your own," said Kate
Purmal, CEO of U3. Applications on a U3-compliant USB drive are not tied to
a
 
specific laptop or desktop, but are installed and launchable directly off
the drive, Purmal said. 
 
The capability to run applications directly off USB smart drives gives
mobile users the choice of whether to work off their laptop or safely use a
public
computer, Purmal said. Users are already
 
happy with the simplicity and portability of USB drives, she said. "You just
plug them in and they work," Purmal said. 
 
Supporting Products
 
Verbatim will include U3's smart computing platform in its $99 1GB Store 'n'
Go U3 Smart Drive, which is expected to be launched at Demofall. Kingston
will
introduce the DataTraveler line of USB smart drives with capacities of
512MB, priced at $42, and 1GB for $80. SanDisk, which backs U3 financially
along
 
with M-Systems Flash Disk Pioneers, is also expected to announce
U3-compliant smart drives at Demofall. 
 
A few big software vendors are also expected to launch U3-compatible
products at Demofall. Mozilla is expected to announce U3-compliant versions
of the
 
Firefox Web browser and Thunderbird e-mail client. McAfee will announce an
antivirus engine to protect U3 smart drives from viruses. America Online
will
 
announce a version of Winamp that will allow users to play audio and video
files directly off USB smart drives. 
 
Products 
 
already available
 
for U3 smart drives includes Powerhouse Technologies Group's Migo, which can
synchronize office files, folders, and Outlook e-mail data between a
computer
 
and a U3 smart drive. "That's what makes it possible to leave my laptop at
the office and not carry it home, I just carry my U3 [smart drive] home
now,"
 
as Migo synchronizes and sends to the smart drive all the laptop data she
needs, Purmal said. 
 
Siber Systems' Pass2Go, announced in June, lets users store Web site
passwords, contacts, and banking and credit card information on a USB smart
drive.
 
Skype Technologies has a version of its Voice over Internet Protocol product
that lets users carry their Skype account information on U3-compliant drives
 
and make VOIP calls from around the world directly off the drive. 
 
More companies are expected to announce U3-compliant smart drives and
software in the future, Purmal said. 
 
Product Specs
 
Once a U3-compatible smart drive is plugged into a USB 2.0 port, a U3
Launchpad automatically opens so users can run applications from the drive,
Purmal
 
said. When the USB drive is pulled out, system software automatically shuts
down applications running on the USB drive and cleans out data fragments so
 
no personal data is left behind, Purmal said. 
 
The Launchpad also has a menu for drive management and administration as
well as a link that leads users to a Web site where U3-compliant software is
available,
 
Purmal said. 
 
The U3 system software makes it possible for other applications to run
directly off the smart drive. It takes up 6MB of storage and loads up in
about 30
 
seconds after a drive is plugged in, Purmal said. Once the system software
is loaded, software applications load quickly. 
 
"I haven't see any difference between launching [software applications] from
the U3 drive versus launching it from a hard drive," she said. 
 
It currently supports only Windows XP and Windows 2000, and a Linux version
is under works, Purmal said.
