There are two tutorials /sessions this afternoon covering domain aftermarket.
The first session was given by Rob Hall from Momentous.ca.
The salient point from Rob's talk being that the secondary market has become the primary market - much as is the case in real estate. Some people may not agree or approve with that sentiment, but the reality and figures speak for themselves.
Further details of his talk are here, while you can download the slides from the ICANN site
The second session is being chaired by my good friend Jothan Frakes of DomainSponsor and features Mason Cole (SnapNames), Tim Schumacher (Sedo), Tom Murphy (Name Media - owners of Afternic) and Emiliano Pasqualetti (DomainsBot).
You can download the slides of their presentations on the ICANN site.
