Mir Licensing

I think you're making the licensing sound worse than it is.

Mir is GPL and Canonical always reserves the right to change that in 
future versions, as with all Canonical projects.

Canonical cannot ever take away your rights to use existing GPL versions 
of Mir as GPL. Once a version has been released as GPL, that version is 
GPL forever, AFAIK.

Canonical can only relicense "your work" in future if you commit it to 
the Mir project. If however your work is not contributed to the Mir 
project, but depends on it, then so long as you always use a GPL'd 
version of Mir, Canonical has no rights to influence your work.
