For this reason I'm using a set of different VPS servers running on both Linode (UK datacenter) and Slicehost (US datacenter).

So separate datacenters, admin layer, providers and also important: billing.

Running a high available cluster in this setup isn't trivial though, mostly due to network splits. It works quite well for specific purposes where availability is more important than data integrity. (remote monitoring in this case)

That my plan too. By using dual clouds (again in UK and US), we're getting the highest failover protection we can afford. I can't afford our e-commerce platform to be down and the evidence shows that a single cloud is robust enough. We call it "Cloud Docking" :)
