[Hidden-tech] Web Demo advice

[Scott Reed]

Yugma is very affordable and pretty good for this but doesn't offer any 
of the security you require. However, I don't think any service can 
provide what you are asking for. I don't see a way to prevent someone 
from getting screen dumps or even a complete recording of the session. 
The video signals sent to the monitor are sent in the clear even if the 
software displaying the images is using some sort of encryption up to 
that point.
