I don't think there's a need for callbacks to be this complicated in the
network protocol. I'm still thinking about an alternative, but got it
pretty much fleshed out. Don't hold your breath though, I'm sorta busy
with university.
But OTOH, avoiding callbacks under all circumstances shouldn't be one of
the standard's concerns, well-defined callbacks are well possible even
over the network.

I think I may have been looking at the wrong code; will check again.
