PaaS (Platform as a service) for PHP
I have walked a long road, finding out all possible 'AppEngine' for PHP solutions and am still not where I would like to be. Here is what I have seen so far:

 - pagodabox.com
   - I love these guys. They have built the best looking admin interface I have ever seen, combined with great ideas in mind like Memcache, MongoDB support (both coming) and seamless Github deployment. Unfortunately I just learned that they do not support concurrent requests on a single server. The support staffer literally told me I would need an additional server for each concurrent request I will get.
 - phpfog.com
    - Did play a little with it. They do not support GitHub and you are tied to their Git server -you might like this or not. But you also have to pay for boxes. Shouldn't a cloud service give me the opportunity to use multiple machines, but look like one? Here I can only see one instance. So where is the benefit? Less administration?
 - cloudcontrol.com
    - Correct me if I am wrong, but they seem to do pretty much the same as PHPFog.
 - scalarium.com
    - Looks great, costs a lot. If it actually does what it promisses, the only one that really seams to make sense to me. Did not get a chance to try it out yet.

I am dying for alternatives!
