The idea of the protocol is based on OpenAntiVirus ScannerDaemon's POST
command, with some enhancements.

That's it.

Do you mean STREAM should support an optional argument for a number of
sockets clamd should start waiting on ? No problem.

This problem has been already reported a few days ago. The port number
range will be configurable in clamav.conf.

Oh, I don't think this is a good idea - it will make the command socket
a bottleneck because a scan process for may be long and we can't depend
on the backlog argument of the listen() function due to portability
reasons.

clamscan doesn't connect to clamd at all. clamdscan uses STREAM while
reading from a standard input, but this is not yet fully implemented.
clamdscan will support "remote scanning" (with something like
"--remote-host" option) soon.
