Mobile Aware Mobile Integration Server and Rails

There's a little bit of a discussion about user-agent string detection
and mobile device attribute databases here
http://www.ruby-forum.com/topic/160278#new

but they mention open source ones.

Has anyone got experience using Ruby On Rails with Mobile Aware's Mobile
Integration Server?

You can dl a free dev copy from their website.

Just want to know before I plough ahead with testing this if anyone has
got them working together.
