OK, if I really can't then I will have to resort to two different licenses
as you suggest. However, there are significant advantages to keeping it
all in one license:
o People using a modified version of the software, under the copyleft,
should have the right to sublicense to end users too. Someone who
depends on being able to earn a living "selling" software to end
users might feel that they also depend on the ability of the
community to take over development of WebMacro if I go away.
So I want to take another kick at this can:
You may distribute and sublicense your derivative work to third
party end users with whom you have an existing business relationship,
possibly in exchange for a fee, providing that you place it
under a license which permits only use (including making backups)
of the software, and forbids any other copying, distribution,
lending, or adaptation of your derivative work.
If this still isn't going to work then I guess I'll give up on this
clause and write a separate, probably simpler license allowing
commercial use of my software under limited circumstnaces.
However it seems to me that if I am entitled to sepcify a copyleft
term (which becomes the license for third party recipients) then
I ought to be able to do this on exactly the same legal basis.
