IMHO if their project is licensed and their individual files are not licensed it's a non-issue at least as that is concerned.
If what was said was true about just using a snippet and I'm understanding this thread correctly, then let's give them a attribution / reference back to the source and call it good. My vote would be that Justin can go off on his own and communicate with them without the general consensus of the PMC. If we would like to put it to an official vote we can so this can be put to rest. Until then I'm expressing a -1 for convoluting another project. -Mark
