Thanks for the pointer to that! It was pretty easy to drop them both into TopoFusion. For sure the mapquest version of the OSM tiles will be in the next release. Open aerial, too. Unfortunately it looks like the open aerial doesn't add anything (yet) that TF doesn't already have. It's the same NASA data that TF's Landsat uses, and in the US it is very similar to the "Color" layer already in TF.
Hopefully they find some good sources of non-US aerial data over time. The different view on the mapquest OSM tiles will be a nice add too.
Thanks.
