I am only using Mac OS X at the moment.

Well, I trying to use RunRev, I can communicate using other languages
ok. It's really the lack of any decent documentation or a robust
sample app that shows what you need to tweak in order to make it work
in the real world.

That's what I mean, there is no documentation that I can find that
shows how to do this. I've found some sample code that was useful to
get going, but it's not well documented and it isn't really "real-life".

I am sending very small packets at the moment, maybe 30 characters
max. If and when I get this bit working it will send larger packets,
but the maximum will still be less that 2K.

Not much help here, I can't do an NAK because the server is not
supposed to respond to a Client that isn't in the "Allowed" list.
Thanks a lot
All the Best
