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

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

Low priority:
- config file version (a la sendmail)
- loop detection
- cfg. file reload
- flags for using names or ip adresses in Via ?

- handle SIGCHLD, SIGHUP
- use a  standard lex compatible .lex format (instead of flex)

- make install
- init.d scripts (and rc.local? for *BSD or Slackware)
- man page
- autoconf scripts
- Debian package build files
- the same for rpm
- the same for FreeBSD and Slackware
