Not very. Lots of tedious work. Well, depending on how many packages  
you've installed...

You're a little off there. There are next to zero packages (if any)  
that are dependencies of medley-package-config. As a result of having  
a ton of repos enabled via medley-package-config, you may have  
installed a bunch of 3rd-party packages, but they aren't dependencies  
of medley-package-config.

And for the record, its more that there are conflicting/overlapping  
packages in third-party repos, not that they're entirely  
incompatible. You do have to pick and choose some, but if you're  
careful, they all can mix together just fine. I do just that quite  
frequently. There's some discussion on the fedora-devel list right  
now about trying to minimize these overlaps.

Not that I know of. It could be done with some scripting though.  
Something along the lines of querying your rpm database for packages  
ending in certain repo tags, probably with a custom query format you  
could parse... Then rpm -e --nodeps the package, then use a depsolver  
of your choice to install that package from the set of repositories  
you do want enabled.

Its equally odd (and seriously bad) that its so easy to buy a gun and  
shoot yourself, but so hard to undo the effects. :)
