Glynn: you say that the CDDL is just an attempt to stop the proliferation of software licenses, yet the end result appears to be yet another license.
I realise that many of the changes in the CDDL with respect to the MPL make sense (e.g. not fixing choice of legal jurisdiction into the license), but it is still another license for people to digest.
Of course, this complaint would be invalidated if many of the projects using the MPL or one of its variants switched to the CDDL instead. Has Sun approached anyone about doing so? (e.g. Mozilla, Cairo, etc).
update: I guess it is possible that such a license merger is under discussion.
