WaveRT and ASIO4All with Echo Cards

I've been watching the Echo Audio waveRT development with interest. When they get it happening it should be MOST EXCELLENT!

Has anyone tried Asio4All? http://www.asio4all.com/

I'm getting a new laptop with Vista and I thought I might use the Echo Indigo waveRT drivers with Asio4All and see what happens. Sounds like everything is supported (more or less!)

Anyone have any experience with this?
