You are both probably right. I have to use something else than DirectPlay then.
It is a shame, though. DirectPlay is service provider independent while others (including OpenPlay) only supports TCP/IP on all platforms. This is the most important protocol but I would still like to support direct modem connections, IPX, null-modems, etc.
I took a look at OpenPlay. It is given in source code meaning that in principle can be ported to any system (providing that to proper drivers are written). A Linux version is under development but is not done. For know only Mac and Windows versions exist.
If anybody knows any other programs for platform/service independant commiunication please let me know.
