I've a feeling people are going to interpret the "merge a depsolver into 
rpm" thing in various different ways, lets clarify this a bit:

I'm talking about means of having all the rpm-related tools use the same 
abstract dependency resolution algorithm though an API. Whether that is 
/in/ rpm, or something that rpm itself /uses/ (and possibly further 
exports via its own API) is not terribly relevant to that goal.

What I'm NOT talking about is turning rpm into 
yum/zif/apt/smart/zypp/urpmi kind of tool which deal with concrete 
repositories, downloading information from them etc.
