Given modularization, it could change from our current one-size-fits-all policy. For instance, I think there would be little argument against allowing new app/* modules to be GPL, and allowing new lib/* modules to be LGPL would also seem reasonable. From the perspective of my employer and it's software releases (not that this is an official corporate statement, or anything beyond my opinion of what I think we'd be likely to agree to), those both seem fine. Our requirement is that we be able to ship the Xorg server with the best available drivers for the hardware, and that we allow hardware vendors to ship drivers that they keep closed for whatever reason (3rd party licenses, support of features like Macrovision or HDCP, or just confusion). We also have to support software vendors shipping apps under other licenses (including closed source) that call the X11 libraries. We're glad that market pressures have gotten companies like Intel & ATI to be more open with their drivers & docs, and hope more will follow, but can't refuse to support those hardware vendors who haven't. Obviously, we've learned in the OS space that the ideas our predecessors had in the 90's about taking the X11 sources and forking with proprietary "value add" doesn't work as well as simply participating in and shipping open source, and we're now open source as well for most of our X11 stack - again, simple market forces and economics worked, without the license forcing our hands. The MIT/X11 license meets those requirements without the turmoil and work of relicensing a 21 year old code base with hundreds of copyright holders, but something like LGPL or a MPL/CDDL family license, that requires publishing sources/modifications only to the X server itself and not to all linked or loaded modules could possibly work as well - but then we're back to the question of whether such a change is really worth all that work? Pretty much all vendors I know of actively shipping Xorg are making their sources available, and I really don't see many people saying "I'd contribute to Xorg if only it was GPL" - certainly not more than the people saying that they'd stop if it was forced GPL. -- -Alan Coopersmith- alan.coopersmith <at> sun.com Sun Microsystems, Inc. - X Window System Engineering
