Followup on Exhibit B licences

[Timothy McIntyre]

These are interesting points.  Earlier in this thread, there was mention 
that licensees who use "MPL + attribution" -style licenses have 
overlooked the so-called 'ASP loophole.'  I work for Terracotta, and we 
distribute our software under the Terracotta Public License, which is 
MPL w/ attribution (i.e., redistributed software must contain 'Powered 
by Terracotta' text in any UI).  When we were deciding on our license, 
we wanted to address the ASP loophole, so we ended up revising the 
original language of the MPL.  Wherever software distribution is 
mentioned in the license, we added the phrase "or otherwise makes 
available," in order to cover passive types of distribution, such as 
with ASPs.  This modification to the MPL also appears in the CDDL.
