Yesterday I bought the eye-fi SD card for my camera
www.eye.fi
It works great. I had it up and running in like 3 minutes, and it saves
a lot of time uploading the tons of pictures that I take all the time at
various customer locations.
Also of possible interest to some, it supports geotagging (via Skyhook
Wireless http://www.eye.fi/services/geotagging/) and Wayport access
points if you pay a little extra each year.
Seeing how well it worked on Windows, I started googling for various
f/oss tools that work with it and found the following

Some of the things this tool (apparently) does (haven't tried it yet):
* Scan for wireless networks
* Add, remove and test wireless networks (WPA-PSK with ASCII key
and unsecured for now)
* Reboot the card
* List configured networks on the card
* Fetch the card's unique key and MAC address
Here is some cool config stuff you can do (not f/oss related, but
interesting nonetheless if you're interesting in tweaking it)

And here's a blog on getting the eye-fi working on Linux
