I agree it's probably a joke, but I'm not so sure that the core idea is actually impossible... I could reasonably see a SaaS that simply provides a quick and dirty key-val store. The code is just a translation from REST to REDIS which could easily be done in 2 lines, the value-add is the hosting.

That'd actually be pretty helpful for initial prototyping, where you want to have state shared across devices but don't want to bother with hosting a backend at first, and localhost wont work because the client wants to play with it too.
