The less kernel patches required, the better I like it.

The simpler it is the better I like it (both from a maintenance as well
as a security point of view). Complex -> much code -> many bugs. Much
configuration -> much time and many mistakes that are hard to find.

Also have a look at cipe.
- It's not a standard (no co-op with Cisco and friends).
- It's a module without kernel patches.
- It runs on most Microsoft platforms.
- It uses UDP for transport (never use TCP for serious tunnelling).
- It's got one small config file (and even that causes enough problems
to those who don't know - their networking basics).
- It supports IPTABLES NAT and bridging.
- There is some version confusion right now (I'm using a snapshot till
that sorts itself out).
- It's got a good security track record.
- I used it for years and am very satisfied.

So it fits my taste and requirements best. You should have a look around
and decide for yourself.
