Thanks, Ciaran, for the discussion and very useful information.
It indeed helps, and pretty much coincides with (and clarifies)
my original thinking -- not much reason (for me) to use the lgpl.
I hadn't seen why-not-lgpl.html before, but have read it now.
And I've replied to the email lgpl request, informing him
that mimetex will remain gpl'ed.  Thanks again,
