Well.. I meant to keep a list of IPs to send data too with it.  Like
whenever data is sent, the server looks at that list then sends the
data to each IP on that list.  But I see what your saying with
threads, although my knowledge of threads is a bit limited; I'm heard
of them but have not really gotten into using them.

I know databases, but I've never used them with c or c++ only php.

So I guess I'll go into looking up threads.
