Benson:

Forces is looking between the control plane and the data forwarding plane. The IRS work is focused on contacting between a control program and the routing process on the routing control plane.

At a high level, I think there is a different assumption about where the 
control-plane resides. In IRS the forwarding and control planes might be 
co-resident in the router (i.e. not "separated"), and the IRS protocol 
would be a way of extending limited control over routing state to 
external applications.

If I understand ForCES correctly (which is possibly not the case) then I 
imagine it could be used in a similar architecture and/or as a protocol 
layer for IRS. But the first step in the context of IRS is to make a 
problem statement, understand requirements, etc.

Others might have more intelligent comments, which I welcome. :) But 
please let me know if this perspective helps clarify things, and/or if 
I'm missing some ideas that I should understand better, etc.

Cheers,
-Benson
