DNEM41  developers please keep working on this! yes iChat is better, but this is the only program so far that allows me to screen share (and control) with my girlfriend (who has a Windows).

if you could pretty much copy everything iChat does and transfer those capabilities to Yuuguu, you will win! the capability to screen share with Windows users is a game-winner right there.

(btw - i hear Apple's workin on iChat for Windows. they already have iTunes and Safari. i guess iChat's next...)

KEDOS  Excellent beta software. It works beautifully. However, the new iChat has made it unnecessary in many situations - the only time any mac user would need to use Yuuguu is if they want to share with a Windows user. Fortunately for Yuuguu, most computer users are Windows users. It's also nice that Yuuguu allows you the option to only share your screen, rather than having to share control.

Still, I think Yuuguu needs to stay ahead of the game. It's a bit buggy, as it's betaware. For instance, whenever I open it, it's hidden. I have to ask someone to message me in order to view the Yuuguu window. Also, I hate that it opens in the top left (right on windows) corner every time, and wish it would remember where I left it last. Just a minor problem.

To stay ahead of the game, it would be awesome to include video\audio chat with it. File transfers would be nice too (drag\drop into the window? oooo)

Keep up the great work, developers.

If a similar feature ever gets integrated into Skype\Aim\Yahoo, Yuuguu will go in the recycle bin. Got to keep ahead of the game, which it is so far.
