Oh great. yet another way for ad services and botnets to talk to eachother...

Because yeah, that's where this is going to be used first and foremost.

Most people are not intelligent enough to understand how to secure their internet banking, and now we're going to bake-in hosting tcp connectable servers?

These security prompts better have some real clear language and require giving permissions every time.

Now I can see some good things for this too, start a flyweb from your desktop and easily transfer some stuff from your phone for instance (something that still sucks in 2016)

I just think that most of it's use will be malicious.
