I'd recommend just picking the most liberal license you're comfortable  
with.  The uses permitted by an MIT license are a superset of the uses  
permitted by the [L]GPL, so offering it under both has no advantage  
over just offering it under the MIT license.

If astng is released under the LGPL rather than GPL it's fine to  
import and use it from pythonscope.  Although, if you would like to  
have a chance of getting it back into the Python stdlib in some 3.x  
release you'd need to use a license like MIT or BSD.

There's also Armin's high-level wrapper to the _ast module released  
under the Python License:
http://lucumr.pocoo.org/cogitations/2008/03/30/high-level-ast-module-for-python/

It doesn't have a fall-back to the compiler module yet, but I'm sure  
that could be added if you need an alternative AST API.
