We used one of these for Viento last year, it's a pretty nice box. We used
it more as an ATM-to-HIPPI gateway, and were getting about 80Mb/s between the
two interfaces (I don't have my actual data handy, that number could be
wrong). I believe NASA Lewis uses one as a HIPPI router too, there
might be something interesting on their web page. It's essentially a high-
speed switch connected to a PC running gated. It's been a couple of months
since I talked to the folks at Netstar, but they were planning on doing IP
over SONNET for just the reasons other people on this list have mentioned.

if anyone's interested.
