Friendly URLs for community objects

Hi,

Does anyone have any experience of using friendly URLs with the community API e.g. replacing /forum/roompage/?roomid=20 with something like /forumname/roomname or for a topic /forum/roompage/topicpage/?topicid=5 with /forumname/roomname/topicname

I'm assuming this is possible just not sure the best way to implement so any suggestions gratefully received.

Thanks,

Mark
