Only the plugins licensed from third parties where the developers didn't offer to unlock them for us. Initially, there were many, but back in December most of them (e.g. AAS, Overloud) were kind enough to supply licenses to SONAR users.
I haven't checked recently to see which ones are still locked to SONAR*.EXE, and it's possible at this date that maybe there aren't any anymore. I just didn't want to promise full compatibility and have someone come back with "oh yeh? what about PerfectSpace?".
All else is in doubt, so this is the truth I cling to.
