Andrea,

To elaborate on what Dmitri said, I would like to license the widget
library used for the IPAv2 WebUI under GPLv3+ or LGPLv3+, but
unfortunately there's a weird gotcha that prevents IPA under "GPLv2
only" from using any (L)GPLv3 libraries.

This wouldn't be a problem if IPA was "GPLv2 or later" instead of "GPLv2
only", but I think the consensus is that as long as we make any change
to the IPA license, we might as well migrate to "GPLv3 or later" (or at
least that's my opinion).

Although the widget library is the first place we encountered this
gotcha with "GPLv2 only", I'm sure it will come up again in the near
future, especially as IPA has such a plugin-focused architecture.  If I
understand the situation correctly, as it stands now you can't write an
IPA plugin that links to (um, imports) any (L)GPLv3 libraries/modules,
which is obviously far too restrictive and really limits what the
community can do with the code.  So sooner or later we're going to have
to make this change.

In an internal email conversation, Simo pointed me to this helpful
chart:

Thoughts?


Cheers,
Jason
