Syncing Pages with a Mac running Lion

I really like the idea of Pages documents being in sync between my devices.

However, my Mac won't run Mountain Lion, just Lion.

Is there any form of hack that would allow me to,use the Mountain Lion version of iWorks with the sync folders on my iMac?

I've looked at alternatives like Dropbox but these don't automatically keep everything in sync as iCloud does.

Thanks

Phil
