I would also like to see MPL 2.0.
The only reason the CDDL exists is because Sun wanted a license that would prevent Solaris kernel code (ZFS etc) being used in the Linux kernel.
I also think the MPL or Apache license seem to be better choices if you don't want to go LGPL/GPL.
Hm. Not sure why FLTK uses LGPLv2 with static linking exception.
Of course, it is allowed to redistribute source code and object files, because they are not linked at all.
Correction: MPL 2.0 is compatible, but older aren't.
You're right I don't think it's worth the trouble. I wouldn't mind the code being licensed under MPL 2.0 but If we're talking about licenses worth switching to then I would prefer the FreeBSD or Apache license. Switching from CDDL to MPL to me seems like a good waste of time and effort for little real gain imo.
