I think the issue was not data, but lack of cooperation in the sense
of checking against the other 3rd party repos on package conflicts.

That's probably already the problem. What 300 (!) package conlfict
between which repos? I know that I'm trying to keep ATrpms 100%
conflict free with CentOS5 for example (pm-utils was a bug that was
now fixed)

See the example for the different packaging of clamav where you might
get a different set of clamav subpackages gathered from different
repos due to priorities setups. You don't actually protect the system
but you add to its destabilizaton, it's a false sense of security.

Bottom line is: The issue with package conflicts need to be fixed by
humans, not filters - the first step is to allow users the choice of a
pure add-on repo and a mixed one (like ATrpms does with abusing
"stable" and "testing" repos). The next step is cooperating with other
repos to avoid any clashes up to the point that these repos may get
merged. That's what rpmrepo.org is about.
