Here are some FlightAware results for his 707, N707JT. Before Halloween he was cruising around Florida in it (last stop Greystone, his home airport in Oscala, FL). A flight hasn't been picked up by flightaware since then.
Anyone else know the N-numbers for his other aircraft? I'm sure we could track them down with FlightAware and see if his destinations are covered by LiveATC.
UPDATE: I looked through the thread over at JC, and I saw that his new eclipse jet is N218JT. And right now, it's on its way from St. Pete/Clearwater to Greystone. Must've been visiting family for Thanksgiving. Don't think that flight will be on any feeds.
Another update: I searched through the FAA N-number registry for G2's with N-numbers ending in "JT" and
found N492JT and it is registered to the same company the eclipse is registered to. So that's another one of his birds. And his last flight was from LAX-17FL (Greystone) on Nov. 20th. So if anyone is interested and has the time you could look through the LAX archive for his departure.

Also, I noticed he's only VFR rated, so he's probably not up front for many of his trips.
