Well, I tried the following approach. The thing was that on the start of
application the license was checked and some of the extension points
were added on the fly, if the license was appropriate.
There is even a hacky approach where you have to use reflection to
obtain a private object of some class managing the extension and using
that object you can remove the desired extension point.
You can use the first approach - it is "legal", so to speak, but the
second one is hacky, so you will probably be better showing some warning
messages in a wizard explaining why it does not want to work.
I can not provide you with details, how I did it. Try searching. I
explained the first approach in detail in of the topics about a year ago.
