I have had mixed success with wirenode, but the concept that you can take an existing site like this one and turn it into a mobile site is pretty cool.
Try Zinadoo or MoFuse as well.
Check out Garrisonsites Mobile at http://garrisonsites.mofuse.mobi and see what you think. It took less than a minute to set up.
I expect to see many more sites like these in the near future.
