I have a client that uses a similar setup with SQL Server. They've yet to test it but they like what they've got thus far. Just make sure you've done a business impact analysis and are focusing on the right things before spending money and effort on it.

If you are using a reputable vendors synchronous replication, the only potential pitfall would be to make sure you have all of the database LUNs in a consistency group. This will guard against rolling failures corrupting your copy.

If it is asynch, things are a lot more complicated.
