	OCCAID has a pop here in Atlanta (3 actually).  Not sure about HE.
Last time I looked, the closest HE pop was in Miami but they've been
expanding.  Problem there is that both OCCAID and HE are SIT only.  They
really don't have a provision for IPv6 over UDP and that's the problem
he's having with his DSL modem and the tunnel.  I'm with OCCAID
including full BGP peering (at one point that was the only way you could
get a full /48 was to peer BGP with them to control the dynamic
routing).  Now, OCCAID is using SixXS as their frontend, end user
management, but the SixXS IPv6-in-UDP protocol (AYIYA) is only available
over in Europe, last I looked.
