Prevent screen recording / scraping of videos + Updated AWS pricing for M3 instances

Hello,

Is there any way to add a watermark or a tracking caption / subtitle to dissuade users from using screen capture to download streaming videos?

Also, can you lock down access by IP?

Also, is the pricing model on Adobe Media Server 5 on Amazon Web Services - Pricing up to date? The current EC2 generation is M3 -- do the same pricing guidelines apply to M3 instances?

Thank you for your help, Karamjeet
