Port 80 is HTTP standard; many servers running Bitcoin are also running websites, so I doubt that would work. AFAIK, though, just switching ports in the client software would work.

<p>Bitcoin can be configured to handle any port for both peer-to-peer communication, as well as JSON RPCs. However, as Bitcoin clients do not encrypt their messages, it would still be fairly easy to filter out Bitcoin-related activities. One could then switch to using Bitcoin through TOR, or the developers could implement message encryption if needed be.</p>
