At first, I felt that the need to download special frontends will be required and hence this would slow down the moment - it will be really stupid if you had to download a special frontend from everyone.
But guess what?
Now you are seeing vendors requiring you to download special frontends! Microsoft has its LIVE plans, Adobe has its Apollo flash, Google has its download agents, like Google Desktop, Google Earth, Yahoo is the same game, and with the video explosion, new you are beginning to see new ventures that will require new special downloads!!
For video, it seems the fight for consumer mindset be Microsoft (Media Player) vs Adobe (Flash) vs Apple (QuickTime). Could you imagine having to have three TV Cable Boxes, one for each vendor just to watch TV? Someone has to grab this and create a universal standard here.
