No? It would be good to know why. Also, Telepathy now has a high-level
File Transfer API. If you can afford to depend on the development builds
of Sugar (soon to be released as 0.84), then this might make your life
much easier regardless of which solution you choose.

As has been noted elsewhere, this might one day be available to all
Activities, by having Sugar provide a view-only VNC server. That isn't
tremendously difficult (VNC over Telepathy has already been demonstrated)
but no one's stepped up to implement it. In fact, implementing this might
be easier than writing your own image-sharing system.

Remember that Telepathy is providing an abstraction layer over Jabber.
Chat is simply using Jabber's basic IM functionality. I doubt you'll be
able to use Chat as a model for sharing images.
