[c-nsp] 3560G as WAN-aggregation-layer

[Tony Varriale]

Care to share your server farm experience?

There are many that do what you are trying to do as long as you understand 
the limitations and differences in QoS/etc (compared to routers).

G1s, although being part of a software platform, are decent horsepower.  If 
you are looking at some shaping/policing down from gig you may want to be 
careful (especially on multiple).  But, if it's a 100mb line and you want to 
play they will do fairly well.
