You list quite a few changes that are required for this to work and some affect the manifest - I am not against that in any way and as long as 1.0 isn't out I am fine with changing the API (i.e. the structure of the manifest). However: besides the (albeit cool) feature of being able to hold the apt-cache in memory I don't see a whole lot of advantages of using python-apt right now - so: is it worth it?
