Yuuguu's approach to screen-sharing goes straight through your instant messaging clients, although they're not required to run the program. It's a multiprotocol messaging program that supports the biggest IM services--Yahoo, MSN, Google, AIM, ICQ, and Skype--in the hopes that rolling the services into one package will appeal to resource-conscience users.
When you want to initiate a sharing session, you click on the users' name and share the provided code. As with its competitors, both sides must agree to the share before it can begin. Unfortunately, Yuuguu doesn't support file-sharing, although you can transfer files via IM.
Yuuguu users can share with as many as 29 others, but only the host needs to have the software installed. Participants can watch and contribute to the chat, making this an effective tool for small-scale presentations. It supports voice chat, too. Of the various screen-sharing apps out there, Yuuguu's instant-messaging support makes it among the most Web 2.0-esque of the bunch. If those features are what you need, Yuuguu's a good choice for you.
Yuuguu is a communications tool that enables instant messaging, screen sharing, and conference calling, among other features. Add your team members or clients via the "Find Contacts" button at the top of your contact window to build a network of people with which to collaborate. Click on a contact and choose "Chat" to open up an instant chat window for quick messaging and group chat. At the top of your chat window you will see the "Show" button. Click this to share your screen with the people in your chat window. When in screen share mode, the viewer is able to request control of your machine and is allowed only with your acceptance.
Every conversation is allocated it's own private global conference bridge. This is always displayed at the top of your conversation window. Everyone in your current conversation will be shown the same PIN number - so at any time you can all dial the number shown, enter the PIN number and be placed instantly into a voice conference. Each participant can change the dial in number shown by clicking on the underlined country name by the dial in number.
