Or is there a password, it's encrypted, and shows a counter how many user agents have hit the page and option to destroy after a single view like firefox-send?
kudos for not having sex or porn in your terms of service.
as a possible user, when it comes to video like things - I am skeptical of free - it's unsustainable, and leads to some sort of later bad (obtrusive ads and tracking, business disappears over night - all data loss, worse things.)
I'd feel better if it said something like ' to keep the service accessible to all, a free option is available at very low resolution, with a registered account you can send XX number of HD views per month without tracking.. as a premium service you get XX number of shares with HD audio and video - enterprise options available..
something like that.
that way I feel the company has skin in the game and won;t go corrupt or belly up - or is really just a three letter agency watering hole in the first place.
If it take off it will become a target for botnets - if I was going to use it regularly I'd need to know that experienced people were watching server logs and had multiple layers of bot protection and such.
random thoughts - love the idea. Screen sharing can lead to all sorts of password details, bank details and all sorts of other things leaking unintentionally - guaranteed digital shredding would be nice on top of other things.
