Last piece of follow-up.  Perhaps Apple will consider relaxing (and 
in some sense extending) its present license of Squeak, at least, to 
the terms of the APSL, so that Squeak's license can at least rise to 
the level of a full-scale viral GPL-style license.  I have not 
studies APSL carefully, but it appears to be a substantially more 
modern version of the GPL, addressing patent as well as copyright 
issues in the manner of the Mozilla license.

I'll give it a read-over this weekend, but perhaps the Disney lawyers 
ought to consider the opportunities this provides for Squeak and the 
Squeak community, at last "freeing" the last vestiges, if any, of the 
original Apple heritage.
