Lets say you make a map and someone wants the data.
First, are you acting in the spirit of the license? Let's assume yes.
That gets you 99% of the way there, despite your technical detail analysis.
Next, you don't have to make the database available. You can make the db
available, or the code.
Next, you could ship that with the work. So each paper map could carry a
cd with the code, or something.
Next, you could just put a dump or code snippet up somewhere. Storage
space is effectively free at this point, or dropping exponentially.
If linksys can distribute hundreds of millions of routers and maintain
GPL by sharing the code, surely you can too?

This is an except from a message I sent to Steve. But hopefully
someone can answer these questions for me (and for everyone who wants
to comply with the ODbL):
"If you publicly use any adapted version of this database, or works
produced from an adapted database, you must also offer that adapted
database under the ODbL."
How long do I have to keep a copy of the adapted database in case
someone takes me up on my offer? How much of the database do I need
to keep? Is the offer valid to third parties? If person A makes a
bunch of tiles from a database, and person B prints out a map from
those tiles and gives the map to person C, who offers person C the
copy of the adapted database? (Person B likely doesn't have a copy,
but Person A would have to keep a ton of obsolete data indefinitely if
his offer is valid to third parties.)
As of right now I have produced hundreds of thousands of tiles from a
myriad of different versions of a myriad of different databases. If
someone asked me to give them a copy of the adapted database, I
couldn't possibly comply.
