I was thinking of using JPEG to actually enclose the profile data. Since
embedding the profile in an image is permitted, we would make these JPEG
redistributable, no strings attached.  That's called a loophole. Off
course, IANAL.

This is not Dual Licensing. Dual Licensing is non discriminatory. This
one is, as you have to use one OR the other depending on who you are:
End user or distributor.
Dual Licensing is often not recommended and usually used to address
license compatibility issues.

The problem is not whether it is is good or not. The problem is
redistribution. Open Source software is meant to be redistributed by
whoever want to do so. End-user, software developer, ISV, etc. This
"End-User" license clearly prevent the user from redistributing.

That is all the problem. Redistributing some color profiles part of an
open source project should not make said project liable on behalf of the
originator. Open Source software is often distributed without warranty
or liability. The GPL is a good example of said warranty, but is not the
only one.

That said license be changed to have the following clause:

1/ disclaimer of liability. Files are provided as-is without warranty.

2/ copyright retaining: files are copyrighted by the copyright holder.

3/ free redistribution: files can be freely redistributed as long as
said copyright is kept. They should be kept *Verbatim*, or the profile
has to be changed (to make sure that we still have correct profile,
because this is the whole purpose of the profile redistribution.

This IMHO does not cause a problem for GPL software because it is not
code, it can be redistributed, it can be replaced with something else
(other profiles), etc. and it fit the need to have *genuine* color profiles.

Off course IANAL.
