Usage tracking of JBoss tools

We would like to know how many actually use jboss tools.

We got some data from eclipse update sites but they are unreliable.

Better if we could do a simple ping to a server to track when eclipse is started with JBoss Tools.

Default will be on, but should be easy to disable.

Default should not track more than what a visit to a webpage tracks.

Suggestion is to use Google Analytics to track it.

jgoogleanalytics could be a good basis for this. http://code.google.com/p/jgoogleanalytics/

Other requirements:
Should not ping more than once a day (per workspace or per eclipse instance ?, per workspace I would say)
Should be done asynchronosuly to not have any UI delays
Should have some way to anonymously track users so we don't skew the usage data
