I've always seen it as sort of an "every other MUD does this, it must
be a good idea" solution. I think most people who start writing a MUD
server concern themselves first and foremost with making a good *MUD*
instead of with making a good DB core, a good object model, and a good
communications link. Those who do try to get into those areas seem to
go with the object model and the DB more than the communications.

Don't mention this communications model on any kind of network
programming forum, though. You'll never hear the end of how stupid you
are. ;)

That's pretty much what I consider the "ideal" model, myself. I don't
do it, because I'm still not entirely comfortable with threads, but
I'm working on getting there. Currently, I still use select() for I/O,
just because... well, every other MUD uses it. :P
