MTA's are sort-of system wide by nature, since only one thing can be 
listening on the inbound port.  I'm more concerned with different JVMs 
since it is fairly likely that some users/applications won't be 
satisfied with included version(s), and some apps that you might want to 
run at the same time require different JVM versions.

I haven't found documentation for the alternatives system that explains 
it at that level, and I haven't had a strong enough stomach to wade my 
way through the multi-level symlink morass to figure out what the right 
values for JAVA_HOME and PATH should be to execute any specific JVM 
version.  Is it really designed to handle that?
