I disagree.  By your description there is no problem scaling the current
model to much bigger numbers of prefixes and paths.  Then why not simply
do it???  Apparently there ain't a problem then?

For routing you have to ways: The BGP (DFZ) way or the aggregation (by
whatever arbitrary level/layer divider de jour) way.  If you have third,
different (not just a modification or merge of partial aspects of the
former two) you may be eglible for a Nobel prize in mathematics in a
few decades.  They run behind a bit, you know...
