You may not have to wait as long as you think.  The slides below were
presented at the most recent RPS WG meeting:


The idea is to provide a means to specify the aggregation boundary
within the IRR and provide the tools to transform that specification
into router configurations.  I'm not sure the slides are entirely
self explanitory, but I think they convey the general idea.

This work is progressing.  Gradually, but it is progressing.  ANS
should have working code to do this deployed by next IETF.  This code
will enable ANS to do much better aggregation that we now do
regardless as to whether other providers buy into the idea.  To
accomplish the type of multiprovider cooperation you refer to above,
it is a matter of getting someone else doing the same thing, or
something similar enough that we have someone to cooperate with.
