Netclasses is an easy to use interface to socket programming in Objective-C with GNUstep. The core netclasses supports virtually any protocol, but the distribution comes with everything needed for TCP/IP (opening ports, background connections, etc.). Netclasses seamlessly integrates into NSRunLoop, which means there should be no need for redesigning applications to use it. LICENSE: LGPL2 or later WWW: http://netclasses.aeruder.net/
