.net 4 and Sharepoint Server 2007 on same server

My situation is that I developed a .NET 4 bas开发者_如何学Ced MVC2 web app, and now I have to deploy it on a Windows Server 2003 that has standalone SharePoint 2007 living on it. My quick research shows that SharePoint 2007 doesn't play with .NET 4. So my questions are:

1) Will SharePoint 2007 break if I install .NET 4 on the server? As far as I know .NET versions were backwards compatible...

2) Is it possible to deploy the .NET 4 assemblies with my web app without actually installing the framework and registering it.

3) Any other tips and advises on resolving this situation?

SharePoint wont'break if you apply latest service packs + cumulative updates to it. At least I have such a combination running on my servers right now.

It would be a problem, if you tried installing .Net4.0 on the same machine prior to "Infrastructure update" of 2009 (or maybe before SP2?), since, as it was said "SharePoint stored some references to .net4 classes in the configuration database", whatever that means.
