- better Via parsing (handle ' ' in uri, eg: foo.bar : 1234 ; received=) and
 ipv6 addresses ([fec0:aa::01]).

High priority:
- reply ("response line")
- default route ?
- add To-tag
- add User-Agent
- drop ACKs for our replies
- icmp error handling
- ipv6 support

Low priority:
- loop detection
- cfg. file reload
- flags for using names or ip adresses in Via ?
