Multi-domains compatibility with comments+ and ultimate facebook

Hi Guys,

I'm using Ultimate Facebook and comments+ on my network. I want to start using multiple domains plugin, but I am afraid that using different domains will mess up the social integration that depend on the domain names.

I can't find any information that this is supported by the plugins.

So my question is: Is the Multiple domains plugin compatible with Comments+ and Ultimate facebook? This in a (public) multidomain scenario, where users can choose which domain they will create their subdomain on they blog. E.g. user1.domainA.com or user1.domainB.com.

Thanks!
