Guys,
I will do this / collaborate on this. I already manage an open source data logger that connects arduino to google's cloud computing infrastrucure. I have the time, resources and interest to keep something like this going. I have the code to put up a full text search web site with user authentication
Please contact me if there already is a site that's been started if you just need my help.
I own the domain opensourceloggers.com which i will donate to this cause
