Following up the failover approach, we are deploying with two orion
instances on separate hardware with full failover (orion has a very easily
configured clustering) and a similarly clustered database, with a
load-balancing router on the front. Our hosting provider has given us a
100% SLA with this architecture (with some support involvement on our part)
which means we can offer this same level of availability to our clients.
So to answer your question 2), the best (price/performance) alternative as
a failover for orion is, umm, another orion!

Dan/tastapod.
