On the download Experience

Any chance you could assist with Hi-Res download?

I prefer to download as I can watch at 1.5 speed with full fidelity. Unfortunately the 3.5Gb High res download takes took long. The web site appears the throttle back the download to 200 - 400Kbps after a while. This means that after 4-6 hrs it times out. So I now have 8 almost complete downloads.

Any change of splitting the Keynote download into Part 1 & Part 2. & offering that as an additional way to download the keynote. The other sessions are fine.

It is great that MS is providing a more competitive way to create sites, & simplifying the "How do I get it hosted" & "how can I find an ISP that supports SQL" aspects.
