At Game Summit? I think I'd be down for that. I'm in the same boat, actually; bought it ages ago, haven't gotten a game in yet. Haven't even read the character creation stuff! Don't know how long I'll be needed for the Dominion tourney on Saturday, but other than the Resin casting on Sunday, it's wide open.
As for playing a Xenos... There'll be two Xenos options for a Rogue Trader supplement coming out in a few months. One isn't announced yet, but the other is confirmed as an Ork Freeboota.
And YES, they have rules for what happens when his spores start growing into grots and squigs. Which is awesome.
