MII (MIM Integrity) is a component of MIM. That is the part that is
basically a GRS equivalent since it is an integrity manager. And yes,
you can share across sysplex boundaries unless you put the control
file in a CF as Ted said.  MII will not get around the sysplex
sharing restrictions for sharing PDSE and HFS - which must be 
shared within the scope of a sysplex (because the ENQs are issued
with RNL=NO). Search the archives for more (much more!) on this.   

MIA (MIM Allocation) is the tape sharing component.  TDAM would
be a similar product (as well as IBM ATS).  MIA can be licensed 
on its own and I have worked at many shops that did just that. 

There are other MIM components also.  For example MIC (MIM Console)
which lets you share consoles and route commands to other systems
similar to the way it works in a sysplex environment (but again, 
it can be used across sysplex boundaries).
