Have any of you heard of roboearth or it's open source cloud engine Rapyuta.? Rapyuta is a cloud software that allows robots to offload their heavy computational work to the cloud. It also allows robots connected to the cloud to share resources. When used in sympathy with roboearth network, it share data with other robots all over the world. From what I have gathered on Rapyuta wikipage, it does seem possible for a pi running ROS to use as a brainor running as interface between the server and hardware. I cannot say for certain having no prior skill with Servers of any kind.
I am including the links to roboearth website, rapyuta website and a popular science article on it
