Is he using Qwest Cable Modem, or Qwest DSL?

I don't know about their DSL, but for their cable modem service, they
assign private (10.0.0.0/8) addresses, and NAT them to the internet.
However, they will assign a static IP (at no additional charge, last I
checked) for use in remote access/VPN/etc.  They do block some ports
inbound,though.  I don't; know the exact list, but it's along the
lines of 21, 80, and 443 (to discourage running servers, although in
this age of P2P, I think you'd see less bandwidth use allowing those
ports than you'll see on P2P ports).

This is what made me wonder if it's Qwest Cable Modem.

Can he reach you?  If so, an alternative might be running VNC over
something like OpenVPN.  That will increase the security, and give you
full connectivity between the machines over a single open port.
