I agree whole-heartedly. Sockets are naturally binary and confining them  
in clumsy text-oriented IOStreams interface is IMHO rather a bad idea.

Also, one can not just wrap a TCP socket in an std::iostream, feed it to  
code writing into std::ostream and expect good performance. The reason is  
TCP mechanics: you pretty much always need corking (TCP_CORK), so you'll  
end up having to output an intermediate IO manipulator before the actual  
output, so that it corks up the socket upon construction and uncork it  
upon destruction, or having to use a corked socket by default and uncork  
it in ostream::flush. Say good bye to genericity...
