Imagine if the Ubisoft always-on DRM were an inherent, unremoveable aspect of the game system rather than just something tacked on to a few individual games after the fact, such that Ubisoft couldn't even begrudgingly neuter it in a patch. Well, this is even worse than that would be.
The game doesn't even run locally. All you get is streaming video/audio and all the lag you'd expect (including controller lag), which is a recipe for disaster in North America (before you even consider data caps).
Let's say you're lucky enough to have a 30mb/s connection. Why would you want to use it to transfer your game's video instead of, uh, a DVI cable, which is capable of 4 Gb/s? The people who developed DVI apparently understood that that 1920 x 1200 pixels w/ 24 bits/pixels @ 60Hz results in bandwidth well over 3 Gb/s. The people who push this stuff seem very, very confused (at best).
Some people consider IPS monitors unsuitable for games requiring fast reflexes (i.e. FPSes) due to their double-digit response times. Internet latency is often worse and certainly more unpredictable than LCD monitor response time, and with this tech it applies to audio and keyboard/controller/etc input too.
Those of us who know anything about bandwidth and compression and (especially) latency can see the enormous technical obstacles facing a service like this, and no one has ever done anything to explain how they intend to solve them. Onlive did everything they could to lock out independent reviewers with NDAs and closed demonstrations. A friend of mine described it as the gaming equivalent of the perpetual motion scam, and IMO that's spot on (except that it would still have the draconian DRM issues even if it worked perfectly).
Streaming games appear designed from the ground up to benefit the game publishers and fuck the customers, exactly what you'd expect from any DRM system.
