Misses all the udp ports though.

UDP port scan is not reliable and can be terribly slow. You'll need
ten hours (not counting retransmit) to scan a Solaris, for example. 
It can be intrusive too.

And we do not have the equivalent of find_service* for UDP.
Doing it would be slow and intrusive:
1) Most UDP services ignore broken requests
2) Other UDP services crash when they receive such requests.

There is no silver bullet on this topic.

If you really need the list of UDP ports, SNMP or netstat are probably
the best ways to get it.
