On a related note, there's also something called "server affinity",
which is a kind of load-balancing override for license conservation as
you suggest.
The way this works is, say for example you have some licensed
application installed on two different servers. When the user starts
their first copy of this application, a server is selected according to
whatever load-balancing property you may have set. When the second
instance is started, since this user has already started a copy of the
application, this second instance will be started on the same server as
the first. This is called server affinity, and is designed to prevent a
user from consuming excess application licenses. IIRC, this originally
had Microsoft Office CAL's in mind, but since Office is licensed per
client device, I don't really think this applies, at least not
anymore. See:
http://docs.sun.com/source/820-1088/t3loadbal_config.html#affinity
(Whenever I discuss Microsoft licensing, I promptly get a visit from a
large, hairy "lawyer" who reminds me that I really shouldn't speak about
Microsoft licensing policies, and reinforces that with a very hard kick
to a very soft place. So, anything I say about Microsoft licensing is
probably wrong. Actually, anything I say here is probably wrong, so
take it all with a grain of salt. )
As for TSCALs, what David wrote is correct - I'll just add that the
location of your issued license is your local registry (for a
Windows-based computer) or the SGD server itself for non-Windows clients
(see: http://docs.sun.com/source/820-1088/tta_tscal.html), with the
source of the license your local license server..

SGD does open a separate RDP session for each application. However,
multiple applications from the same user/device (depending on how WTS
is licensed) should consume one TS CAL only. Are you seeing evidence
that multiple TS CALs being consumed from multiple applications
launched by the same user/device?

Sorry for not explaining my question clearly.
When we create Windows applications (e.g. Word, Excel, Powerpoint,
etc) on SGD, each of these Windows applications consumes 1 Microsoft
client access license (CAL) upon call up. When there are more Windows
applications to be published through SGD, the number of MS CAL
increases.
I like to know if there is way on SGD to make use of an established
Windows session to call up other applications that reside on the same
server host. Be it a simple configuration or customization to SGD
itself.
Thank you.

I notice that each Windows application establishes one client
session to a Windows server when open and hence uses up one terminal
service license.
Is there setting in SGD such that multiple Windows applications can
share the same Windows user session?
Thank you.
