Has anyone successfully used Multipool as a target pool through the Flexible Mining Proxy? cdhowie, have you tried it?

I've seen at least 2-3 reports in addition to mine claiming it doesn't work, and nobody saying it works for them.

No signup or setup is needed -- just connect to http://multipool.hpc.tw:8337 with a Bitcoin address as your username, and anything for your password.  I'd be interested to hear if multipool is broken for everyone....
