- Your ID information, plus your address, and business registration if you have.
Webcam and Phone conversation must conduct.
There are heaps of escrows that have held over millions of dollars and have not had a video chat or given their id.
When you are essentially forcing an escrow (who should already be trusted and would have no need to verify his/her id) to give your their real name, address, you are basically opening up a whole new road which can lead to you either extorting/blackmailing the escrow to release funds (you have his/hers address remember).
The other 2 terms are fine.
I would seriously encourage you to change your terms, all you are going to get are some desperate people willing to give you their id and address for some bitcoins.
PS- Also try to get an escrow supporting multi-sig, makes things safer.
