What are Artist 7 restrictions with recording over internet

I have a friend who wants to get Artist 7 but is interested to record with me with my full version of Cubase 7 over the internet. What restricitons will he have if any if we want to record together over the internet? It was not clear to me on the comparrison chart.

None whatsoever, he doesn’t even need Cubase as far as I know.
Artist doesn’t allow you to be on the recording, but on the performing side all you need is the little app that should be available for free.
