       Yes - that could be improved by having the metaserver verify the hostname

Yeah, that is why I used php to get round that, flock and apache deal with all of that.

Freeciv constructs HTTP POSTs and sends them to a single metaserver, I haven't been able to find the metaserver code as yet, but the server code is quite nice...
