"Microsoft is working closely with ICL to enable a rich and never-before-seen experience online, with innovative features allowing Internet users to switch between multiple camera angles, broadcast feeds, overlay with statistical elements and even interact with tools that will, for example, allow users to judge and opine the fate of a player when a third umpire decision is called for."
ICL is providing Live feed of all Indian Cricket League matches going on at present using Silverlight.
UPDATE : I just noticed, Not only the scorecard, you can watch the match LIVE, which uses Silverlight streaming.
"We plan to use the internet as a huge medium to reach out to enthusiasts and fans, with live broadcasts, recorded highlights, scoreboards, statistics, charts - all providing Internet viewers with a great alternate channel to enjoy matches as they happen," said Kapil Dev, president, ICL.
