I'm really looking forward to reading it.
I myself can come up with very good arguments for IP:
(1) Most successful jurisdictions in an Anarcho-Capitalist society (ex. charter cities, universities, business alliances, etc) would
voluntarily recreate some form of IP on the basis of contract law, because it will constitute a competitive advantage for them to do so.
(2) I also have great respect for the Objectivist perspective and the related epistemological arguments.
(3) Mind uploading, self-owning information-based life-forms, information is life,
etc, etc, etc.
None of this would apply to the situation at present, however.
