While there are software apps that will already let you use multiple IM programs, the Dutch have now made it possible to chat from virtually any computer or mobile device. eBuddy provides Web and mobile instant messaging services, enabling you to chat with your MSN, Yahoo and AIM contacts without actually having to download or install any software.
It is a free Web based messenger that will let you chat with your existing buddies, and no registration is required. The Web version only requires a Javascript enabled browser, and it can be accessed even from behind a firewall. You simply login as you would with your regular account. The mobile version works with any device that supports xHTML or WAP, and this includes mobile phones, smart phones, wireless PDAs, and even the Sony PSP or Nintendo DS.
