The list will know that a few years ago I was very enthusuastic
about ATM. I put in a leading edge ATM network at a hospital in
the UK for medical imaging. I was a proponent of using ATM for clustering.

These days, I would say the idea is not so good.
You get built-in Gigabit network interfaces on many motherboards,
and Gigabit switches are really cheap.
