Of course but I said the video should be proven to be made before announcing it to the public, e.g. from 2007. And how well, I dont know

But I think you can get pretty far with video forensics. So stuff visible in the background and so on. Like I said can still be doubted, but could be very convincing depending what is in it.
No need for fancy video forensics partner... just have live television in the background and have him sign a PGP with his message. That should do the trick.

... I still think Satoshi would come up
with a very unique way, if he wanted to come back.. He or she has the knowledge to do just that. I am still waiting for the time, when the headlines in the news will read "
Satoshi Nakamoto is back "
We have enough skilled Bitcoin developers who could help out, if we really needed someone to identify him or her.
