GagaLive - Real time chat room, counter, hosting

GagaLive - Real time chat room, counter, hosting. This is a nice looking resource. You can add a chat box anywhere that will accept HTML. According to the developer, you can have several versions, all linking to the same chat room. It can also take over 500 users in the same room. Although the features are basic, it's very fast and impressive. Take a look!

Meebo rooms. Meebo is well known for offering funky little gadgets that allow you to chat via IM without having to install anything. They've now gone to the next level and created chat rooms that you can embed onto a page.

If other people have also done the same thing it's possible for people to get together across chat boxes to talk about the same things. I've seen it described as IRC for dummies, and I can see where that's coming from. It's not yet ready for prime time and they're still doing private beta testing, but it's worth keeping an eye open for.
