Most of those don't look very interesting for dual licencing (which I think is mainly good for software libraries that might be useful for non-free software - Qt being a prime example), with a possible big exception for the utouch stack. I can see though that some might be good for open core (e.g. plugins to use Bazaar in combination with some proprietary systems that don't interest FLOSS developers enough for them to produce free alternatives, or integrating some of the infrastructure tools into semi-proprietary phone OSes).
Personally I wish Canonical success in pulling that off and still keep the juicy bits FLOSS.
