I agree it would be useful, but I think it's just as useful to have it 
be separate. After all, it seems a little wierd to have JRuby hooked up 
to a repository that might contain gems it can't run and for which 
there's no equivalent port. But perhaps that's just me...I like to only 
have the gems installed I'm using, and frequently have a couple 
different JRuby instances to use for different purposes. But then again, 
I'm doing lots of demos and active JRuby dev...so there's a lot of churn.

At any rate, it ought to work fine, but the jgem thing seems to me 
totally unrelated. gem install should be gem install, whether on JRuby 
or MatzRuby.
