There is supposed to be webstreaming on the Rotterdam site (Dutch version only), but it's not been working so far. http://www.abnamrowtt.nl/
Enter the site, and you'll find yourself on the Dutch home page (the streaming options are not available on the English version of the site).
At the bottom you will see a section called "Photogallery, filmbeelden en meer". Click on the option "Op TV / Radio" which will take you to another page.
In the box entitled "Uitzendtijden TV / Filmarchief 2005" you'll see dates, times of operation with narrow and broadband options. The icon or text turns into a hyperlink when it is available.
Unfortunately, it has not been available for me yet this week. The same happened last year, but by the end of the week it was working fine, and the final was certainly streamed out live. However, it is possible they have implemented some sort of ip checking to only make it available to folks in the Netherlands like the BBC does for some UK coverage. Let's hope not!
You might find that the live scoreboard on the site doesn't launch properly.
Use this for Centre court: http://wtt.networkoperations.nl/frameset.html
and this for court one: http://wtt.networkoperations.nl/baan/frameset.html
Currently Schalken and Pavel are at the sharp end of the third set. Federer will be on in just under an hour (I hope)
