Is there likely to be support for other clouds in the future? Amazon is great and you're far cheaper than Heroku itself but I'd love to throw this on DigitalOcean or Vultr.
Vultr's website looks... interesting. And their control panel is also... interesting. BUT. I've been very impressed by the performance of my nodes. Tops DigitalOcean easily. I don't have any hard numbers (I can provide some if people would like) but with the performance and number of locations they provide it's hard to beat. $50 credits for two months: http://vultr.com/freetrial Vultr also offers a "dedicated cloud"…
When I've run tests, they beat DO on every metric on unixbench (for equivalently priced/RAM filled instances [0][1]) and they let you use whichever ISOs/images you want (including fun stuff like BSD), unlike DO.
Their SATA storage nodes are really handy too.
You didn't post numbers but here are mine:
