In addition to Aamer's comments in re Cisco NFC, commercial folks such  
as Arbor, Lancope, Mazu, Narus, Q1, et. al. have various scalable  
options for collection/analysis.  One can also scale the various open- 
source solutions based upon choice of hardware/OS.

With regards to telemetry volume, folks really need to start thinking  
about scaling their DCNs (vital telemetry such as NetFlow should be  
sent over the DCN, not in-band on the production network, for obvious  
reasons) to accommodate higher volumes with higher speeds, as well as  
increased amounts of information from features like FNF, the NetFlow- 
based layer-7-type reportage via NetFlow v9 transport of the new ASA  
and the SCE, et. al.  The growing sentiment seems to be that  
classification capabilities *must* keep up with the higher link speeds  
which are becoming more commonplace.
