OT: Can anyone name projects which are released as free open-source and under a commercial license?

isync has asked for the wisdom of the Perl Monks concerning the following question:

Hi fellow Monks,

slightly off-topic, but I would like to know if anyone can name me a few projects, possibly Perl related, that release their code under an open-source *and* a commercial license. I think mostly differentiating between non-commercial and commercial use.

A quick brainstorm on my side just brought up KyotoCabinet and JW Player. Any more, well-known?

Movable Type springs to mind: Movable Type (wikipedia), Movable Type (Open Source) and Movable Type (commercial license). And it is written in Perl.

MySQL seems the obvious one. Qt also. `package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name`	[reply]

MySQL was the first one I thought of too. Also RHEL, xv (not free as such - read the doc for full details), Asterisk and probably many more.	[reply]
