Scott Johnson mentioned this morning Feedster is looking heavily at NYU’s Coral distributed content system as a possible solution to RSS bandwidth issues. Coral operates over port 8090 and is therefore blocked by most firewalls. Your domain name server must also be aware of DNAME records. Good idea but it needs some kinks worked out for widespread use. BitTorrent uses ports 6881 to 6889 and is therefore blocked by most firewalls as well. Port usage has not stopped the widespread use of BitTorrent, although BitTorrent users are highly technical. A good conversation topic for tonight’s Feedster Developer Dinner at 7 p.m. at Vino e Cucina in San Francisco.
