Yes, Zapatec.com runs their stuff this way. Probably others as well.
> Are there any design considerations?
I don't know. Probably.

Not specific to PostgreSQL. I'm sure there are generic benchmarks. Keep
in mind that PostgreSQL needs lots of 2-way I/O, batch writes, and random
reads.

See above. Also keep in mind that PostgreSQL's use of I/O should improve
100% in version 7.5.
