Disaster Recovery with master-master replication

I am looking at setting up a Disaster Recovery (DRSite) for my company, and have been looking at the possibility of master-master replication.

e.g. everything is written to a MySQL DB on my main site, and then replicated to a remote MySQL DB.

In the event of catastrophe (e.g. a prolonged power / internet outage), we switch our DNS to look at our DRSite (possibly using Amazon EC2).

Then when everything is better, we change back again.

This seems a good idea, right up to the point where I need to move back to the main site, but I can't see how I would easily move back to the main site. As there would inevitably be a short period where we inadvertently write to both masters.

(obviously a really prolonged outage would require the DB to be rebuilt, as it would take too long to re-read all the binary logs).

Does anyone have experience of a similar setup, and what would be a good way to go about this?
