Hi Jack:    (01)

I continue to give serious consideration to the matter of the Nooron
license.  The LGPL and the X11 license are the current contenders, both
being GPL-compatible free software licenses.  What with several 
categories of the actual runtime user-contributable contents of Nooron
containing executable code, the "strong copyleft" [viral] qualities of
the GPL are beginning to appear to me to be rather too restrictive.      (02)

I expect I will but it is far from a top priority.    (03)

Please expand on this if you mean other than that running modified GPLed code 
on a server does not constitute a distribution of that code and hence does not 
require (under the GPL) the publication of the modified source.
To be clear (and I apologize for not being so in my previous messaage) GraphViz 
is not under the GPL, it is under the AT&T Public License which has problems as 
listed here (about 80% down) [oh for purple numbers!]:
