I have made new experimental pluggable transports bundles with support for the websocket transport. We hope this transport looks enough like HTTP to get past certain firewall filters.

If the transport name websocket sounds familiar, that's because it's the same transport used by flash proxy. The difference here is that you connect directly to the bridge, rather than going through a browser proxy. The actual software is the websocket-client program from here: https://gitweb.torproject.org/flashproxy.git/tree/HEAD:/websocket-transport
Due to a build SNAFU, the OS X packages have the flashproxy transport disabled, with only obfs2, obfs3, and direct websocket enabled. The other platforms have all transports enabled.
We would like to have some more fast websocket relays to include in the default torrc in a future release. If you can do this, see the section "How to run a relay" from https://gitweb.torproject.org/flashproxy.git/blob/93be0302:/README#l100 Send the IP address and port of your relay to tor-assistants@lists.torproject.org.
