Jybe is a Peer to Peer plug-in that enables people to surf the web and chat together all in real time. This is not a proxy service but turns your web browser into a de-facto IM client.
Why do I blog this? I like this co-surfing idea even though I still have to think about creative and original scenarios of use. Anyway, it's another element to take into account in the interface discussion I had yesterday: in this case, the browser is the main interface and is the basis for IM. Let's test this now.
