We have had no problems. There was a delay back in the day when we had to share the mouse to play online, ver. 7 & 8. But with the advent of V.9 and Netplay, that is not the case. Mainly due to people using HiSpeed access. On a dial up, there may be a lag, but if people are just watching the game, it will get caught up eventually. The host being on HiSpeed would probably help alot.

I am surprised more people don't use this.

It is great for H2H play using the audio. Definitely makes the tastey adult beverages flow better.

But being able to use it to watch other's play, is a great addition to any league, especially during the post season.
