(No problem. I appreciate your work towards better python bindings!)

Yes, we've tried swig at that time as well for a different python library.
The maintenance work and lack of precision (because of the abstraction)
made us

Until those plans come to be, we should select the better abstraction
I guess. (I do not have much experience with CFFI [1], the challenge will
be to map the C api of gpgme to an object oriented pythonic interface.)

Why did you choose porting pyme over pygpgme?
Which one do you consider more pythonic?

The challenge I see is that if there is an official python-gpgme
in a week or so, this API will need to be supported for a longer time.
Even if the implementation underneath could be completely replaced, 
the python API probably could not. So if pygpgme offers the better 
abstraction now, making the pyme abstraction official 
may pose a problem for the future.

Best,
Bernhard
