This would be very cool!

It would be useful for memoize in any form, but especially if one didn't
have to close one PDF before opening another. What memoize does is ship
out pages during the normal output to the "primary" document, so it
would really help if after shipping out the externalized page, one could
return to the primary document.

I suspect that in the case of multi-pdf output, the issue of forward
references (as far as I understand it correctly) will expand into an
issue of references full-stop.

I assumed that Jonathan Kew would be among the recipients of this
mailing list. Where is he reachable?

Best,
