[GSoC 2012] Planned API changes - RFC

Support for message delivery notifications sounds very reasonable in
general.  I'm not sure I understand your suggestion, however; it seems
like message delivery should be per-message, while typing notification
is per-conversation.  I would suggest that we implement it per-message
if at all possible.  I would imagine this can be done with message ID
and styles in webkit, although it may not be worth trying to attempt
it in imhtml.

Yes, nearly all of server.h is slated to disappear, eventually.  It's
a remnant from before libpurple provided a coherent API to
applications, and libpurple/pidgin were one monolithic application.
