MIT copyrights in X.org source base...

All over our source base, we have N different variants of the MIT
license, and often N variants that differ solely by the name of the
person or company named as the copyright holder.  For example, attached
for you amusement and revulsion, is the 109 lines of copyrights found in
xserver/dix/events.c.  On this file, we have 1 TOG notice, 2 Digital
Equipment Corporation notices (!), along with a Sun Microsystems notice.

Due to the Digital/Compaq/HP merger, and X.org's successor-in-interest
to TOG, I think we have a chance to clean this up greatly. Scott
Peterson, who is HP's lawyer on Free software and Open Source law has
agreed in principle to letting us merge the Digital/Compaq/HP
copyrights, and I propose we do so with X.org owned copyrights as well.
If we can come up with exact language (nearly) everyone can agree with,
maybe we can also get other companies and many individuals to change to
a standard form as well, allowing us to go down to 1 line/copyright
holder.

Sometimes something like the following is also in the license:
        "Except as contained in this notice, the copyright holders and
        authors names shall not be used in advertising or otherwise to
        promote the sale, use or other dealings in this Software without
        prior written authorization."
Scott doesn't think this is necessary (other laws prevent using your
name in vain without your permission), but he's also happy to see it
included if people will be more comfortable with its inclusion.

I'd like people's opinions on whether inclusion of that boiler plate is
really necessary.

I'm also troubled by the "both that copyright notice and this permission
notice appear in supporting documentation" clause, though changing this
may be more controversial.  I call this the "tree killer" clause.  At
the time we drafted the MIT license, no one anticipated aggregate Linux
distributions with thousands or tens of thousands of contributors.
Technically, if you followed this to the letter, and distribute a
printed document, you end up with much paper pulp covered with copyright
statements; it doesn't matter in electronic form nearly so much: storage
is cheap. I'm wondering if we should make the clause "both that
copyright notice and this permission notice appear in supporting
electronic documentation" to help save the planet.

Here's an example result of what I propose:
