Now there's probably several huge reasons the concept wouldn't work

But perhaps there's some amount of data locality that can be exploited
to make this work. If there's at least one type of information that
we can use to seek through the file and find perhaps a country or a
boundary of some sort, then it could be possible.
Well, for one things, the nodes, ways and relations are
represented separately. I've already split the OSM file into these
segments because there are times I want to do a scan, and only want to
scan one of these things. It would also be logical to break things up
into big geographical chunks, say, continents, countries, etc.
