Well, network name resolution ist quite different from the hostname. I'd
check DNS A and PTR records as well as /etc/hosts&Co.

It is not that hard. Depending on what you want to achieve you have
different options. What you describe sounds like a typical 'Freifunk'
setup.
In a typical freifunk network, the participants take care to encrypt
their traffic on application/protocol level, e.g. HTTPS, SSMTP,
SMTP/TLS, IMAPS, IMAP/TLS, ircs, ssh
If that's not possible for some protocol you tunnel it e.g. via
- ssh with portforwarding (single ports, while networks if needed)
- openvpn (networks)
- tinc (networks)

We run OpenVPN on Alix 2D13 encrypting 35MBit/s last time I tested. The
AES crypto unit had not been in use unless it gets autodetected and
autoused.

Check out freifunk&Co, they have quiet a few pages about setup and
information about encrypting traffic as well.
The pages I know are mostly German, but at least some exist in English
versions as well
http://wiki.freifunk.net/Kategorie:English should be an ok entry point.
