You ought to read Mancoosi goals before claiming "admin" POV. Unlike  
LSB packaging,
Mancoosi does have less lofty and more specific goals, more in line  
with distributing software.

  I suppose that qualifies as an "admin" point of view.

And you need to look harder, there are most definitely tools brought  
forward from EDOS,
used/contributed by both Mandriva and Caixa Magica.

Why not compare freeipa.org and Mancoosi yourself?

I'm never sure I've met an ISV. I'll ask if Mancoosi is suitable on  
next meet-up.

And I suppose LSB's "The Berlin API" is a fully fledged release rather  
than a "design"?
