Good question. I don't think there's a public API to do this. Of course,
that doesn't prevent the system from creating databases with ptr-based app
info blocks. There is an API to determine whether a LocalID is ptr-based or
handle-based.

I just looked at the code to beam a database and it definitely assumes that
the app info ID is a local ID on the same card. I wouldn't use the appInfoID
to store arbitrary data. Instead, create a 4-byte app info block and put the
data there.
