Yeah iirc there may be limited channels, but I've not looked at that stuff yet.
Assuming it all works though it will be very nice to just do bakes for certain aspects of tracks.
Ie, Forza 4 seems to use second UV channels for AO baking, then they can use more repeating texture types for things like car interiors and get nicer higher quality materials, but still get AO in there.
In theory with world coord UV for a detail map, then tc0 for a control map (say shading, colour variance etc like the asphalt shader), and then tc1 for AO or 'wetness' or some other cool features, you could get really nice looking and simple to author materials!
I'll have to grab the latest version to test things out and see if it'll play nicely.
