At least, the point (my personal Unumeric showstopper) which bothered me
really vanished :)

I think the author (Pierre Denis) could change his mind and the license
as he does not feel too strong about it (it was more a default choice if
I remember correctly). Anyway, in case of positive answer I will ask him
permission for both the integration and the license change.

The question is more about a formal integration in scipy:
 a) The code is mature, clearly written and not huge (engine code is 600
loc and unit definitions code is 1 loc per unit). Its integration should
not be a big deal.
 b) The package nicely fills a gap in the scientific toolkit.

Hence, is the license the only problem?
