There's a file system protocol used by many digital still cameras, which isn't actually camera-specific. Not MSFT-specific either.
Originally called "Picture Transfer Protocol" (PTP) it's actually more of a remote hierarchical filesystem protocol ... with an event channel (handy for "new picture" or "inserted new flash memory") and some built-in search capabilities ("what JPGs do you have"). The strangest capability was a file type tag, which isn't actually that bizarre.
As with RNDIS, and USB Mass Storage, I understand that support for PTP is part of MS-Windows since about Win2K. So a PTP gadget driver would probably be a useful contribution to Linux.
