[RC5] Problems with RC5 via HTTP proxy

You of course could try the newly emailbased fetch/flush system. 
Send email to "fetch at distributed.net", get blocks within couple of
hours, process, send them back to "flush at distributed.net"
But I think that's not as elegant as the keyproxies
How far did the client proceed? Only networktimeouts or also some
signs of "The proxy says". If you can't check them with the service,
try testing via the CLI-based win32 client.

Maybe post a relevant bit from a logfile here. Some people actually
seem to know what errors like "Error 26/0 4/0" mean.
