Friend
It would be possible and bring some advantages... but is like the old
saying (?): "With great powers comes great responsibility...".
Some advantages of supporting a HID profile (just like you said):
- no need of server
- ready to go with most of major OS (Linux, Macosx, WinXP, etc)
Some disadvantages: AFAIK, HID doesn't support the concept of
screenshot (one of nice features of amora).
:-/
But if you are willing to dive deep on this thing, I'm ok to help.
Best regards
