Of these listed 4 are cable companies, is there something in the cable modem networking that requires deaggregated routes beyond their borders?
No, for the general statement about 'cable modem networking'.
Is the problem that they might have seperate 'networks' for their regional parts and leak more specifics for these parts along with 'backup' routes via aggregates?
This is trivial to do only as far as your $s carry. Aggregate draws the traffic, then NO_EXPORT-tagged longest-match carries the regionalized traffic. Folks do this as a 'best exit' approach between peer netwworks all the time. If you are suggesting disjoint, unconnected islands, then they should be separate ASNs for sane paths; see charter's islands, the pre-271 refleif ILEC LATA-bound islands, etc. -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE
