I have watched TAR matches on my iPad. You just have to download a browser from the app store called Skyfire. Skyfire will play any flash site on your iPad. Here is a link to a pdf I made up for my blog a year or so ago that tells you how to get and use the browser.
I watched the US Open match between SVB and Jose Parica tonight on accu-stats, on my iPad using the Skyfire browser. It worked great! Here is a screenshot off my iPad.
