Like I said in my last post, the personal proxy could be placed on a
machine that did nothing else (I.e. a 286 or 386 that's just lying around)
and would be restricted to only communicate on the RC5 ports.  In this
way, the worse thing the untrusted code could do would be to send bogus
information to the RC5 servers and/or clients, which would be a stupid
thing for the RC5 organizers to program into _their_ personal proxy code,
or to erase everything on the personal proxy machine's hard drive, which
again would be a stupid thing for the RC5 organizers to put in their code.

This arrangement would in effect be the same as someone else running the
v1/v2 gateway, just that it would be running on your machine.

Maybe to satisfy the policies of an organization such as yours, someone
else would indeed have to setup a v1/v2 gateway that was globably
available, but with an access list as Kris mentioned.
