Ah, looks useful. I actually merged in my own inetd-mode
code for 0.42, though I didn't get it using two seperate
sockets for read/write - have you found a situation which
requires that? I'll see how non-intrusive it is to merge it
into the main codebase, or will put a patch (probably
against 0.43 since the inetd code is already there) on the
website.

Thanks,
