Maybe a stupid idea, but why we just don't prefix the 'jruby' with
'j'?
So we can have lancher in '/usr/bin/jruby'. Similar for irb, gem...
(jirb, jgem, etc...)
Then the shebang will be '#!/usr/bin/jruby' and the MRI version can
cooexist with the jruby.

Yes, we have, but you need to have root privileges to use them. That
is not cool. We believe that something like this script [1] could
make better service.
