Thanks castaway,

it seems pretty much that this is what I was looking for.
I was mentally bound to the idea of froking a new kid for each client and therefore I was thinking of forking another kid that reads the file(s) and sends them to all other client-kids. But this seems to me too complicated for Perl, Perl is smarter (than me). But thank Good, that there are guys like you :-)

I'll soon will try your solutions.
For now thanks a lot,
Carl
