Actually John I think you misunderstand the SISSL (see exerpt of section 3.1 below which states that source covered under the SISSL can ONLY be distributed under the SISSL and as well that additional restrictions may not be imposed). I notice further that MozPL 1.1 has a similar clause, so not sure why you think its okay to sublicense MozPL covered code "under any license". Inability to recombine Mozilla code with GPL'd code was one of the main reasons Mozilla.org community decided to tri-license.

"3.1 Application of License.
The Source Code version of Original Code may be distributed only under the terms of this License or a future version of this License released under Section 6.1, and You must include a copy of this License with every copy of the Source Code You distribute. You may not offer or impose any terms on any Source Code version that alters or restricts the applicable version of this License or the recipients' rights hereunder..."


Also be advised that the complete OO.o codebase is dual-licensed under the LGPL and SISSL. There are no "various parts" under the LGPL.

Right enough, except that Oo.o has various parts under the LGPL, and
all of it is dual-licensed under the SISSL.  The SISSL is an MPLish
license, which provides that any or all of the *unmodified* files of
Oo.o source code can be reused in derivative works under any license.
So this isn't a good example for you, but what you say is undoubtedly
true for pure GPLed code.

Definitely not.  The MPL, like the SISSL, provides for reuse of unmodified
files of source code in derivative works under any license.  It requires
distribution of source only of those files which have been modified, if any.
