Very curious.

traceroute6's take me to various places, so I think it may just be a
simply DNS round-robin rather than anycast.

Now I'm starting to really wonder- I'm having this trouble over a SixXS
tunnel but some of the non-tunnel'd IPv6 environments I have access to
are working fine.  Perhaps the issue here is actually MTU or MSS
related?  I've not had any problem with SSH connections to regular IPv6
hosts (even transferring large files), either inbound or outbound..
