I believe that the p5i should be in lieu of, not addition to, the "pkg" 
type you proposed, as it's a proper superset that will be supported by 
any current release of pkg, both the client and server.  I would suggest 
that it's more properly:

<bundle type="p5i", URI="<file or http URL here>"/>

Yes, that was meant as a later.

I'd like to hear more about the tradeoffs in that discussion, I guess, 
as I sense from other comments that it is desired.  It seems at the 
least you should be taking the requirement to make all URL's only be 
non-interactive for this case so that it can be implemented easily later.
