We operate on multiple regions at PagerDuty. It's slightly painful, but I've nowhere near as bad an experience as you claim. We've done it using Chef to do the heavy lifting. It's worked pretty well. It takes a bit of work and determination, but it comes together in the end. One problem with building on AWS is their lack of network diversity.

Issues in Oregon have caused network degradation between WEST-1 and WEST-2 that last for days with no improvement.
