Hi Kai:

Example of Web incompatibility: the first link you provided earlier 
https://play.renewchannel.com/ does not play in my IE9 browser, which is 
either the #1 or #2 browser on the Web today. I'd say HTML 
incompatibility is a widely recognized phenomenon. Many websites break 
when you try to run them from mobile browsers.

Regarding your comment that "most DOOH deployments use a USB stick" 
today, I do have some reservation. If that were the case, we run the 
danger of dreaming up a fake problem to solve here. Digital signage 
whose content needs to change once a month is more likely than not to 
run on a network today, and most of them already use HTTP as the 
transport. I'd argue they are already "web-based".
