Surprising as it uses linux device mapper, the truecrypt volume is seen like any other linux device. As long as the OS has synced to disk it should be fine? Or is it linked to FAT filesystem?
Anyway, removing an sd card without unmounting is looking for trouble.. Operating system bufferize disk access. I've "broken" FAT filesystem on a poorly designed usb stick like this in windows XP.

The other problem/opportunity I'd like to consider is some sort of interface to file manager - since it supports internal filesystem, memory cards, bluetooth and samba it ought to be possible to add truecrypt volumes.
LUKS uses standard pmount which is used by KDE and HAL. I'll have a look at how pipeline's emelfm2 handles this.

Don't forget that truecrypt is not fully free of use and there are some restrictions in the license if your application is mainly using TrueCrypt. I'm not a lawyer so I'm rather happy if you maintain it
