I installed Vindigo.prc and VSync.prc to GVM, Vindigo became visible as an application and it launched too, however it just asked me to 'sync my handheld'. I don't sync (never did with my real Palm device either), so I don't know if this will work or not.

The known (showstopper types of) problems with GVM are more or less the following:
- There's really no way to get data _out_ of GVM, except by synching: GVM doesn't see the SD cards, and it doesn't see Bluetooth directly. (It sees the network though, so there's a possibility an ftp client could be used. I haven't tested this yet.) (Getting data _in_ is easy enough, as the GVM launcher can _read_ the SD cards.)
- Programs with ARM code don't seem to be supported - m68k code works though.
- (unverified): Programs using 3party libraries (e.g. mathlib.prc) isn't supported (crashes GVM)
