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...
