Or until we have ubiquitous standards. I'm a bit more optimistic than 
you -- and more pessimistic at the same time. 

Back in the last century there was the Desktop Management Task Force.  I 
thought it had become extinct, but it still appears to live as the 
Distributed Management Task Force http://www.dmtf.org/home

As I remember it, DMTF was driven by Intel and their LANDesk Manager 
application to bring SNMP-like monitoring and management to desktop 
computers and applications. License management too.  I researched 
LANDesk, but was using a Symantec offering at the time, which wasn't 
DMTF compliant.  The name of that product escapes me, but it gathered 
equipment inventory, did application distribution and configuration, and 
may even have had some end-user menuing capability.  All this for DOS 
and Win31...

So, even with 15 years of DMTF standards development we still haven't 
reached the point where we can plug it in and it "just works".
