I meant experience with running a repo, but experience in trying to 
coordinate disparate policies is probably more relevant.  It just isn't 
going to happen and everyone might as well recognize that up front.

It would be very useful to me in any case where the versions differ.  I 
like to know what I'm running and why.

If the package name makes the difference visible, can't I "yum remove 
xemacs-myrepo" and "yum install xemacs-otherrepo" depending on which I 
want to have installed?

But there is an improvement if I can see and control what I install and 
  understand the differences.  The names are obfucated now since the 
same name can refer to any of several different things.

That's only a problem if you overwrite each other's files. Put them 
somewhere else.  Yes, having files of the same name in different path 
locations can confuse people who don't understand that path order 
searches have been used since the invention of the tree structured 
directory to permit multiple versions of the same things to co-exist, 
but the concept isn't that difficult.  It's just too bad the package 
managers didn't get it and had to go through contortions after realizing 
that there are things that people need to have multiple versions 
installed at the same time, like the kernel and architecture-dependent

Live and let die, you mean - at least as far as the users are concerned. 
   I don't think this issue has any solution other than separate
