[pgrouting-dev] Licensing for Co-development between OpenGraphRouter and pgRouting

[Anton Patrushev]

Hi Steve,

I believe pgRouting is under GPLv3 - I think we changed from v2 last
year. For me GPL/MIT dual licensing looks a bit strange, I mean I
can't imagine a case when one would prefer GPL.

MIT is GPL compatible and I see no problem with PostGIS which is also under GPL.

By the way, we already have GPL/QPL compatibility issue :)

Anton.
