Comments Plus and Domain Mapping a no-go?

I am assuming that Comments Plus won't work with Domain Mapping - correct?

I'm basing that on the following thread.

It would be SO good if a workaround was found for that. Facebook features would be a fabulous way to generate traffic! But I need to be able to offer my users the agility to use their own domain name.
