I could share a couple of doozies from the bad/ugly arena. However, I generally
go by "Assume it'll work fine, until it doesn't, and then fix that," and I'd say
she would have a ~95% chance of not running into any problems at all, especially
if Ubuntu's xorg stuff were to be used, since it has come preconfigured for
tablets for several versions now. You have not seen the GIMP in action until you
have tried it with a tablet. I dare say, if a tablet PC is not running
GNU/Linux, it might as well be just a PC. Barring certain video chipset quirks,
expect no problems with the projector, either.

This will inevitably obviate a non-computer-related problem: Any such recording
will have picked up not only their voices, but also the speaker-broadcast
versions of their voices simultaneously. If you can find a way around that,
there is literally no end to the list of possible software solutions.
