Seriously ?
I don't anyone in the UK who isn't on a minimum 2Mb broadband.
Most folks on cable are 8Mb slowest package and some are on 50Mb
I watched the video. Interesting and the demos were served from their servers 50 miles away. Not perfect by any means, but showing a LOT of promise.
This isn't an app running in a standard server, they've designed their own server capability (inc hardware) to ensure the performance and pointed out they are "good neighbours" on internet as they do not run symmetric speed.

With better compression, he is the inventor of Quicktime whilst at Apple, that is focussed on the needs of real time gaming then I can comprehend how it woudl be possible to readily deliver SD at 700-1Mb/s and HD at 4Mb/s which is within the min spec thay say for bandwidth. ( eg I've recently downloaded Truth in 24 at 720p HD and it peaks at 4.7Mb/s )

A true MMORPG doesn't send a lot of data until you have a LOT of opelpe in the same area. In the same area then every player has to send movement and actions to ALL other players. WHen done by server rather than p2p this means that evey position has to be sent of every person TO every person. So in a land with 500 people then the MMORPG is wanting to sen 499 object updates to each person. It build up
FFXI is limited to a maximum of 5 people in a group isn't it ? This makes the comms activities much easier ( you don't need to update your model of where your partners are only your opponents )
Games are full of very advanced coding to have predictions in to avoid major warping to handle these extreme cases.
I wish them all the best.
It woudl be nice to see this driving network performance and bandwidth higher rather than waiting for the porn industry
