Thanks for your feedback.

We use Jabber, Gtalk and Skype.

Also about how are we different

- Adds call functionality. Customers can call directly from browser without installing anything new

- Integrates with Skype and Google Talk. Other IMs are around the corner. Hosted in AppEngine and Amazon cloud for scalability and speed (currently is the fastest live-chat)

- Social Tabs - you can customize the widget to show Twitter, Facebook and other social communities.

Let me know if there is any feedback you can give to us.
