David Korn going to submit a slight variation on the ATT license you've already
seen, for a second ATT product. His version will:
A. Require GPL-like source disclosure.
OR
B. Require that you offer service for the product similar to the
service you offer for other similar products.
Encouraging outside support of research software is a mandate for this
particular group's Open Source intellectual property. I think "A" is
going to be sufficient to get the support, given the nature of the product,
but "B" is an explicit acknowledgement of that goal.
Thanks
Bruce
