btw, this is all a very very natural next level step for the beloved-to-me upnp/dlna/miracast protocols.

#openscreenprotocol encompasses those old use cases, allowing one to fling a media file at a device.

but it also promotes these edge devices from dumb stupid media renderers, to full fledged web entities. it's a thicker client architecture. the client is a web page! go to this page, & keep open a comms link back to me while you do so. that's how chromecast works. that's how openscreenprotocol works.

i absolutely positively am over the moon with it all. it's such an incredible & incredibly obvious next step for ubiquotous & pervasive computing, putting the universal platform- the web- in to the devices all about us, & letting us dial in. #ambient #ambientcomputing #mobilecomputing #ubicomp

i don't know why i never tried looking for this before, but ah, #Chromecast: the source, here it is:
https://chromium.googlesource.com/chromium/src/+/master/chromecast/

makes sense. there's tons of devices coming out. for some reason i always thought it required lots of NDAs to even begin. it still probably requires lots of lawyers to make a device- Chromecast i'm told has a root of trust system that you need approval to get in on for it to actually work, but it's cool that there's a start. i hope there's a way to make my Android phone connect to my own development/not-officially-trusted devices!

long term, i'm way more excited about #OpenScreenProtocol. wip. we hope. some day Apple might eat all the cheerios without this work, this is an existential necessity for the web, imo, for secondary screen protocols. hoping hoping hoping to see work pick up again.
