How to Share a GarageBand File With Other iPads With GarageBand Apps?

I want to share my garage band file that I been working on my iMac (OS Lion) with other co-workers on their iPad1 so that they can edit it with their iPad garage band app.
How can I send or share my garage band file with my co-workers iPad even if their iPad are sync with other iTunes library?
Thanks.

maybe you should ask this in a Garage Band support forum…
