The original post was about making time at the Pittsburg NANOG meeting
to talk about solutions to the problem of some exchange routers seeing
tens of thousands (even 100x) paths. The size of a full-Internet route
table is growing (albeit more slowly than it used to), the number of
ASes meeting at the various NAPs and MAEs is increasing, etc. Will the
number of paths heard by some routers at the XPs ever be so large that
they don't fit in the 7000 or 4500m's 64MB of RAM? Possibly (IMHO,
likely). What then? Use lots of filtering to keep the number of paths
heard down and lose flexibility?
Then I ask you to sign a nondisclosure agreement.
Oh, then the whole argument is for naught. 
We've actually been very good (some say too good) about adding
features.
Yes, Cisco is very good about adding software features and even about
allowing its customers to beta test software.
