(sorry for the super-late reply :/ )

Yes, an interface to register "please tell me when we're going to
suspend or have resumed" is probably the right thing.  In fact, the dbus
stuff in that tarball is essentially that, with names specific to
rhythmbox.

That solves part of the problem, and it's probably the 90% solution we
should go with, but it doesn't solve the general problem -- which is
basically user-definable, per-session hooks.  I don't think that's
really worth trying very hard at, but if anybody really wants it, it
takes about 40 lines of python if we've got the interface discussed
above.
