Help! Domain Mapping Configuration problems

Hello!

I have a blog network that is running on WordPress 3.4.1 Multisite and we want to offer our blogger own domain. The problem is if the blogger chooses to have its own domain as the primary, our network not get any statistics on the blog at Google Analytic. The idea now is that they will be able to point their domain to our IP address and mapping it, but do not get the choice to use it as primary. The primary address MUST be the blognetworks own domain / sub domain as the address.

The plugin we use is WordPress MU Domain Mapping Version 0.5.4.2
