Name of related component: Mobile Tracking & Tracking Code (Javascript / ga.js)

Request summary:
(Kind of a crossover between mobile & javascript tracking)
Would love to see an offline-capable javascript tracking code that could buffer up tracking events until communication with the analytics servers was available

Use Cases:
We'd love to be able to track the usage of our offline-capable webapp & PhoneGap app

Have tried using a workaround at http://stackoverflow.com/a/8114887 but there's a rate-limit to it's use, and sending multiple tracking events one at a time (rather than queueing them up into one request) is inefficient
