We definitely don't envision an NSE-100 as an aggregation router for
hundreds of end-sites.  We're thinking about a replacement Internet
peering router with maybe 3 full BGP feeds, GigE and multiple OC-3s.  If
we outgrow the router for Internet, we can purchase an NPE-G100 and use
it as an aggregator.  From my experience the 7606 is an incredible work
horse, but also a glorified switch with reduced features (similar to
PXF) and versatility (no NPE version) at a heavier price point.

Excellent feedback, thank you!
