Ari also said during his keynote at OSiM World that Nokia had no interest in licencing/working on getting Maemo onto non-Nokia devices. It's not yet-another-"standards"-body to prevent fragmentation: it's Nokia's mobile Linux stack.

As Quim says, that's not to say that hacking on a Maemo firmware release to get some bits running on the Pandora won't be quietly ignored. But I can't imagine, say, Adobe being quite so friendly if the Flash player gets extracted out of repository.maemo.org (the password's not hard to figure out) and run on another mobile device without them receiving any money.
