Google Analytics in online and offline app

Hi,

I have been asked to look at using Google Analytics in a specific flash app.
The app is built with MDM Zinc and the intention is to add GA code so the (in this case) slides that are clicked can be tracked.

One of the major issues is that if the app is run offline then the information should be stored somehow and then sent when the app is next run and can find an internet connection.

Has anyone done this before or even know if this is possible?
Although this is built in MDM Zinc I am willing to put into a different software (AIR?) if it can be done.

Can anyone advise?

Thanks in advance.
