I don't have any of the code in question, and don't feel strongly one way or 
the other. However some issues that are worth further discussion:
1. This is a change to the existing license, and potentially needs to be 
approved by all copyright holders. What happens if someone says no?
2. Whether alternatives (such as the patent holders granting a restricted 
patent license for use of techniques potentially covered by patent) are 
compatible with the current license.
3. Whether the plug-in API is sufficiently well defined (in a documentation 
sense, and also in a code stability sense) that this technique is 
practicable.
