I think most residential routers do not understand DCCP and discard it
because DCCP is another transport layer protocol with another 'protocol
number'.

Besides getting p2p-TCP to work through NATs, we might want to look into
RUDP that IETF once explored in the past, and that implements
congestion&flow control like TCP.

http://www.ietf.org/proceedings/99mar/I-D/draft-ietf-sigtran-reliable-udp-00.txt
which was derived from RDP:
- rfc 980 (version 1)
- rfc 1151 (version 2),
