Using sockets is very portable imo. If I remember correctly there's only 2 functions that differ between linux and windows[1]. I'd rather use 2 source files than the whole boost asio/networking library. [1] Those are ioctlsocket vs ioctl, and closesocket vs close. A basic TCP implementation can be cross platform with as little as 2 #ifdef/#endif blocks.
