I think, the concepts, Micheal Tiemann described are the only
ones that the Alliance might accept as a first approach.
This way, some of the advantages of Free Software can not
be gained, but the primary goal of them, to allow proprietary
integration via licenses, would be met very nicely. And in fact,
this model seems to be perfectly in line with their current
aims and policy.

I'd suggest to apply the GNU GPL license for the software.
This way, only Free Software products under GNU GPL itself
could use the library. If they would choose GNU LGPL, proprietary
products could link the library without the special licensing.

However, you should not forget that Free Software is also
commcercial software on demand:
