I think there's a lot of discussion of this on various legal
mailing lists.  There's some arguments related to the difference
between static and dynamic linking.

Why don't you sell the software to your customer, and put it
under the GPL as well?  You don't have to release it to
anybody else - but the customer can if they wish.  Is that
your worry?  If it's GPL, you can more easily tell the
customer they have full source code access, yet you have the
rights to go ahead and sell it again to somebody else :)

Dinesh ... help me out here!  How do people like SuSE manage
to have some parts of their products proprietary?  Clearly
defined APIs, release as 2 components, 1 proprietary, 1 open
source?  Make it client/server?
