I have heard lawyers speak on this subject, and, although I was not 
thoroughly convinced that they were right, it does, at first, sound 
reasonable.

Their claim was that it depended on when the aggregation occurred.

If you simply make the plug-in available so that the end-user makes the 
aggregation, ie, links the plug-in in at run-time, then that does not 
count as a violation of the licence.
