So you mean actually modify the file name that the user types into the file save box and stick _mesh at the end?

That kind of file name alteration might be kind of weird for the case where someone was mainly wanting to generate the mesh file...

The way that might be less weird overall could be to have a plug-in that would do this, it could be something like a "ExportMesh3DM" command that you could install and access from a plug-in menu in the future at some point when I've got a menu for such things set up. That would keep it more totally separated from the regular save mechanism.
