Im having trouble finding resources on what is involved in supporting CNAME aliases. If I have user accounts a yoursubdomain.myapp.com I would like users to be able to create a CNAME record that points yourdomain.com to this. What is involved on my side to get this to work? I understand users will have to add the record to there DNS. Do you I have to do some special stuff on my servers?

I think what you are describing is name-based virtual hosts. You can learn how to configure this on Apache here.

Do you think this is something that could be set up to do it automatically or can it only be done manually?

A: 

Aliases (CNAME records) are like pointers in programming. The target has nothing to do and cannot even prevent being pointed at.
