...but if he gets the author to do the mod and re-release he's ok.

Is it reasonable for someone wanting a particular mod to work on it
themselves before submitting a request to the author; and if it is,
would that be a violation of the license, or allowed because it is
reasonable?  Would this grey area be cleared up if the user notified
the author a modification was being worked on, i.e., the mods will be
submitted back to the author for possible inclusion in a future

I guess, to be safe, a commercial operation should not use any PyQt
code <period> unless they have a commercial license for Qt, 'cause it
is just too tempting to tweak a Python program.
