Rev lends itself nicely to having opened sources, but with Valentina, you
couldn't expose your developer code/serial number to others. If you want to
distribute unserialized Valentina components and you are serious about the
project, you should contact me off list. 

If I were you, Id also carefully evaluate each license. There's even a world
of difference between the various "greater" GPLs, 1,2,3, and then all the
other open source licenses that exist.

We use and support open source too, but anything that goes into Valentina
gets careful investigation first so we don't compromise ourselves or our

What really creeps me out are the extremely viral licenses. We've
contributed to some open source projects where the changes themselves need
to be shared, but not the rest of our source code.

There are a lot of free projects out there, but a lot of them are under
either no licence, non-commercial only or under licenses which arent all
that business friendly.

Something Ive encouraged is using a single, commercial friendly license for
any free code offered through RevOnline, no matter what the source is.
Uniformity makes making decisions so much easier.
