I don't suppose there is anyone who knows people at these
networks (and in particular Sprint Canada, Alternet, IMCI,
iSTAR (also PSI, I guess), or IBM) and would be willing to
contact them and say, "hey, you could and should do better
aggregation"?

You might want to look to see if any of the smaller
networks are downstream from you.  I did, and do.
