This won't work for a lot of opensource projects. GPL is simply not compatible with anything. And since most opensource include tests, the issue of GPL creeping up the chain and contaminating code becomes relevant.
Since you distribute tests which link to both PropEr *and* your own code:
- tests themselves must be GPL, since they link to GPL code
- since tests are now GPL, they cannot link to GPL-incompatible code. Therefore your own code must now become GPL.
I wonder why EPL/MPL is not an option for PropEr?

See Kostis Sagonas' presentation on PropEr on erlang-factory.com. It's much better with video, but video isn't there yet
