Its always interesting to see things like this since eCS has never been strong when it comes to printer support. I for one think this is a great idea for the most part (not sure what happens if your Internet goes down). It is not coming out for a while but when it does, this might be something we can use for our OS of choice.

I like the idea of not having to fiddle with drivers. I hope it works as expected so one could use eCS. 8)
