The work is handled pretty much by the server. The basic infrastructure for
D&D is already implemented - most of what's needed is just implementing the
message handling stuff. Although I haven't sat down and worked it out yet,
I'd assume that it would be a synchronous call with the attachments being
the bitmap token and the flattened message which is to be dropped.
