Ramon has interesting post about scaling Seaside/squeak:

I have also been experimenting with Nginx as load balancer and static files
web server, all on the Amazon ec2 instances, but there is nothing in real
production as of yet.

As for database Gemstone is natural choice, as log as it can fit in your
budget. If not, maybe something very lightweight ansd simple like CouchDB
can fit the bill.

Am I setting myself up for a lot of pain, or is it really practical to use

Nevertheless, I think Seaside is viable option for high activity sites.
