API breakages aside, the idea sounds appealing, but the proposed
function signatures could be improved: the biggest risk I see with
switching from separate function calls to passing the property name as a
string is that you also switch from compile-time checks (for property
name typos, for example) to run-time checks. Have you thought of using
an enum instead for properties?

Bear in mind that you'll probably need to bump the Eina revision in
jhbuild.modules if you do plan on using Eina_Value (and there's been no
stable revision with it yet).
