Well, typically we put one upstream source archive per package. 
What does putting them all in one package gain us? Having to update all
of them if any of them need an update?

The problem here is that upstream has no desire to keep a common
protocol, so you need the exact version on both ends. (If I recall
correctly). So, if you have say a debian box with version foo, you need
version foo on the fedora machine to talk to it. In the past this has
been done with multiple packages where 'yum install unison' gets you
the latest, and if you need an older version you can manually pick and
install that one. 

So, not sure how better to solve this problem than with compatibility
