I agree that  SERVERS_SOCKET_PFINET seems better. I proposed PFINETSERVER just for the compliance with env variables already in use: CRASHSERVER for the crash server and EXECSERVERS for exec.

Good idea. I have considered file descriptor and will think over it.

"SERVERS_SOCKET_PFINET=fd:3 prog 3</path/to/my/pfinet" - what does "prog 3<" mean, three overriding names behind?
