Looks great, I've been looking for a solution like this. What would be really cool is to be able to query public data streams and combine them in way similar to Yahoo Pipes.

I suspect people will also want to run aggregations/rollups of their data and that's something we enable in Streametry [1] in addition to other analytics. I might try to build a a bridge to Sparkfun.
