Subscription Video Content

[Serpstone]

I've never used video other than embedding youtube videos.  This time I want to host my own with encryption for the subscriber content and sample videos for general consumption.  Would love any pointers at all.

I would also like the content to be streamable on ipad etc.  What platform would you use (adobe etc)  and why?

I don't want to start out on one road to discover down the line that it sucks for SEO.  Obviously the subscription content will suck since it will only be available to logged in users, but the rest.....

In a nutshell I want to know how to host video well for SEO and make it shareable, but with the option to also have some of the video content subscription only. (should have put it like that to start with probably.)
