so what, give up?

indeed. and even more, what about the sitation like with the TeX program
itself? It is not distributed under LPPL but essentially in the same spirit:
don't change me unless you are either Don Knuth or change the name.

now in this case there is something else: TeX is going to freeze upon Don's
death: according to his wish the version number will be updated to \pi and the
program never changed afterwards (the one with the name TeX).

okay, i have tried this afternoon to come up with something myself and wrote a
draft license that (perhaps) covers the maintenance problems. I'm  not sure it
is good, but i would invite commments.

if there is no satisfactory conclusion reachable I will most likely stick to
the originally suggested changes and call the LPPL1.3, but perhaps my new
draft can be shaped into something useable.

A diff to the offical version 1.2 is appended below (to see the additions and
modifications seems easier this way) If you want to see the full license text
(to check if "The Program" is suitably defined, etc) combine it via "patch"
with the official version, which is part of every LATeX distribution and can,
of course, also be found at

+ MAINTENANCE OF THE PROGRAM
+ ==========================
+
+ The Program has the status maintained' if the Current Maintainer has
+ made provisions to receive bug reports for The Program (for example,
+ by supplying a valid email address). It is not required for the
+ Current Maintainer to acknowledge or act upon bug reports.
+
+ The Program changes from status maintained' to unmaintained' if the
+ Current Maintainer of the program cannot be reached through the
+ provided means of communication for a period of six months.
+
+ The Program has the status frozen' if the Copyright Holder
+ explicitly states that The Program can only be maintained by the
+ Copyright Holder.
+
+ If The Program is unmaintained you can become the Current Maintainer
+ of The Program through the following steps:
+
+   1. Make a reasonable attempt to trace the Current Maintainer (and
+      Copyright Holder, if the two differ) through the means of
+      Internet Search, etc.
+
+   2a. If this search was successful inquire if The Program is still
+      maintained and if so ask the Current Maintainer to update the
+      communication data.
+
+   2b. Otherwise announce your intention to take over maintenance
+      within the pertinent community (if The Program is a LaTeX
+      program, this could be done, for example, by posting to
+      comp.text.tex)
+
+   3a. If the Current Maintainer was reachable and agreed to pass
+       maintenance of The Program to you, then this takes effect
+       immediately upon announcement.
+
+   3b. Otherwise if the Current Maintainer was unreachable and if after
+      two months your intention was neither challenged by the Current
+      Maintainer nor by other people, you may arrange for a change of
+      The Program to reflect you as the (new) Current Maintainer.
+
+   4. If the previously unreachable Current Maintainer returns within
+      six months he has to be reinitiated as the Current Maintainer
+      upon request.
+
+ A change in the Current Maintainer does not alter the fact that The
+ Program is distributed under the LPPL license.
