Well, the stuff they showed us were more along the SAN server principle for local lans... that was awesome but far from worth the money! very very expensive and my team reckons it will date very fast.
So in the near future I don't see it happening, but certainly later!
I also had my reserves about the consequences of late or non payment too as you mention... I kinda figured that at a certain point, such things would become free like the rest of the internet. Sort of like shops in a mall. You can use the mall for free but the shops pay rent.
I imagine bandwidth issues will go away somewhere in the future but I know what you are saying... the present issues do not allow for limitless fun.
I haz an Xbox... It feels like I'm cheating on my first love - The PC.
Still... I look forward to the next level of gaming entertainment, whatever it may be!
