Best of luck to him. His best bet is probably going to be supplementing longer-haul commuter operations (e.g. Philly-New York, New Haven-New York, etc.) in some way if he can get by the access problems. 25 years back he probably could have cut through the access issues without too much trouble; now, not so much.
The other possibility is that he snags a bid on one of the routes where Amtrak and the state aren't getting along great (I'm assuming, as a non-owner of track in the US, that he'd probably need to work with the state(s) he wanted to operate around). California seems to be getting primed for that, after all...and I highly doubt they'd complain if a private operator came in willing to supply their own equipment.
Edit: There have been rumblings that Virgin wants to bid on operating CAHSR if that ever gets sufficiently completed.
