Net::Server -> tftpd ?

Hello,
did anybody allready try to bulid a tftpd or anything else that needs more
"Socket Fine tuning" on the Net::Server/Net::Server::UDP modules?
We are in a project with just a very few time and I have to consider if we
try it with Net::Server or directly with "Sockets" or "IO::Socket".

BTW: the TTDPd module on cpan just works on Windows Machines.

cheers
Sandro
