[MLB-WIRELESS] more important issues <aka: guerilla radio is by ninjas, for ninjas. Worked for global IP's development!>

[Jason Hecker]

I know some guys who are using CIPE successfully for wireless point to 
point links.  It's very painless to get working.  It encapsulates all IP 
traffic with encrypted UDP packets.  It's Linux oriented but there is an 
NT/2K version which is a bit broken unfortunately.   It's fine for point to 
point links, a la backbone.  I don't think it'll do so well with dynamic 
multipoint as each end needs to be set up with static information.  I think 
a version with public keys is being trialled now and might lend itself to 
multipoint cum dynamic stuff.  Could be talking through my sasafras there 
though...
