Two issues with snapshots - They require Enterprise Edition and you still have the connection issues. If I build a snapshot every 10 minutes and I have a report that runs for 15, either people have to know the name is changing constantly, or they would lose their connections.

Snapshots are a good try, but they're not there either.

It sounds nice, but you have to take into account the other benefits that mirroring gives you - automatic failover primarily. How would you handle the conversations between multiple mirrors and the witness to ensure that each database is in the correct state? It's already somewhat complicated to determine what will happen to each database if connections drop, that complexity would grow exponentially given more servers.

If you are talking asynchronous mirroring then perhaps those issues go away - is there really that much benefit over replication or log shipping though?

The ability to have multiple mirrors, or a waterfall mirror setup would be great. I think you stated it accurately that the setup becomes much more complicated to support this kind of setup. It would be a great technology though.
