Massimo, What specifically are you looking for? All that is needed is to use the already included setup_exe.py The new setup_exe.py from issue 224<http://code.google.com/p/web2py/issues/detail?id=224> which was merged in April (rev 216a13ba21a1<http://code.google.com/p/web2py/source/detail?spec=svn977fba3e16687dd91f150d039a4ef03eec467e68&r=216a13ba21a128f8ba0eb58b35c00a1655fd462a>) should take care of doing the compile & bundling the default apps (btw setup_exe.conf doesn't appear to be in the latest stable source release tho it is in the google repo). Do you just need somebody to run the build script one a windows machine for you? I can certainly do that if needed.
As far as licensing issues I'm no expert. pyODBC is under the MIT license. pymysql is also under the MIT license and web2py is already including it, so I'd think* that we're OK. ~Brian *I am not a lawyer nor have I every played on one TV.
