Hi Nick, I've been off Qt development for a while so my answer may be
missing something that happened in the latest two years :) but I think
your question contains the answer. In fact you could move the check on
the ids in the server and only send the signals to those that match.
This way you'd probably end up sending fewer signals and only to the
relevan threads.

Another solution may be to make the server connect signals and slots
of the threads when they're created, but this may very well be
technically impossible (as I said, I've been away for two years and I
barely remember the basics of Qt despite having been an avid user :)

Anyway I think the best approach here (conceptually speaking) is to go
through a centralized router, which is what you're doing now, except
if you have to exchange a lot of messages that may slow down the whole
thing. I say this because I myself had to do this exact thing and
performance weren't great at all--at least until I managed to greatly
reduce the number of signals emitted.

> P.S. Sorry for my English. I'm studying now.

Never be sorry for this as long as you are understood :)
