As noted Im overseas at the moment (currently in Hong Kong and flying out this afternoon) but to answer some questions above- The VLC doesn't require or alter mesh. If you have the redbaron 20m mesh you can use it with VLC as is.
I am working on a 20m mesh for the VLC project too (I need it to compile the 3D water polygons) and this will be released a little time after the initial VLC-
From early tests, although the new mesh is the same resolution, the detail seems better (computing power and interpolation methods have improved a fair bit since the Red Baron data was created)....probably not worth upgrading if you already have a 20m mesh, but I do want to price it competitively to attract new buyers.
