This question is not entirely Red Hat related, but it's close enough,
IMO. 

I'm curious about the MIT X license terms.  It was my understanding
that you could districute the X source and compiled binaries however
you pleased... but the moment you wanted to make money from a modified
form, without distributing source code, you had to pay to join the X
Consoritum. 

However, the copyright notice on the X source doesn't imply this.  It
implies that you can do whatever you please with it, as long as you
include the copyright notice and don't use their name in advertising.

My question is, what prevents a company from modifing X a little bit,
then selling binary-only X servers?  

Basically, why it comes down to this: why are X Inside, XFree, and so
on, members of the X consortium?  (other than the access to
prereleases) Couldn't they do their business just as Red Hat does?

Thanks in advance.
