Probably not many, but it's quite possible. I've done 1 Gbps streams off a
single box before, it's not much harder to take it out 150ms. Heck for
their 60 second test, you could buy some GigE transit ports from someone
with a STM64 across the pond and not even pay for it in 95th percentile.

And you can't afford 20MB of RAM because...?
