I'd prefer if people forget about BSD/MIT and use ALv2 instead, for the patent clauses.

With the following preferred licenses you'd get explicit patent clauses, in ascending order of copyleft-ness:

ALv2 MPLv2 LGPLv3 GPLv3 AGPLv3

Perhaps the Eclipse Public License would also be an alternative at the same level as MPLv2 but I'm not familiar with it.

Fair point.

ALv2 == Apache License, v2.
