I had considered adding a file with permissions, uid/gid and md5sums which the
test would validate.  But that would require more host magic and we had enough
host magic to solve first.

A simpler solution would be something like this.

chown UUU.GGG file

where UUU and GGG are numeric ids.  But I get an error on the host
doing that.

$ touch joel
$ chown 7.7 joel
chown: changing ownership of `joel': Operation not permitted

I don't see a way in pax to force the uid/gid when you are writing.  It looks
like GNU tar has an option which might do this but the man page says 

 --owner=NAME
              force NAME as owner for added files

I don't know whether using that with the option to use numeric ids will help.
