Have you had to modify CherryPy in some substantive way that you
needed to keep proprietary, as opposed to simply developing content
that CherryPy serves but is completely independent of CherryPy's
license?  

I notice that a heck of a lot of commercial users are using completely
proprietary packages like ASP, whose licenses are far more restrictive
than the GPL.  They don't seem to think it's a problem.  So for most
such users, Karrigell shouldn't be a problem either.  Remember that
the GPL only applies to the code of Karrigell itself, not to stuff
that you write using it.
