The last part in this mails [1] [2] is a part with TUN/TAP under Linux
as host.

If you wandt to use more as one guest, you need a different tun/tap for
every guest and *must* set static routing tables between. The host
ipaddress must set after the coLinux networkdaemon is coming up. That's
why I have a delay 3 seconds.

I think, licpcap would work more easyly. It should be usable. I have
tested it long time ago (version 0.7.1) But, I have no config.

Slirp with different forwardings with different ports on host should
also be usable. Remember, that one guest see the other guest on address
10.0.2.2, not on the real ethernet address.

Well, Linux as host is not good documented. Linux as host is no full
working. It't more for developing and debugging coLinux self.
