Looks like the PiCloud team is joining dropbox but according to their blog post "The PiCloud Platform will continue as an open source project operated by an independent service, Multyvac (http://www.multyvac.com/)."
Yes, the Multyvac launch has been delayed until February 19.
They are supporting much of the PiCloud functionality, but not function publishing, which I used quite a lot. (That was a way you could "publish" a function to PiCloud, and then call it from a RESTful interface. It was a nice way to decouple my computational code from my website, which has very different dependencies.)
I fear it is more oriented toward the use case of doing long running scientific jobs, rather than short Celery-like jobs. I hope for the best.
