Meetro has been out for more than a year (it was launched in June 1, 2005). Meetro is an instant messaging service that works as a standalone client and also integrates with other IM services. With Meetro, you need to only run one messenger to chat with your friends from your AIM, ICQ, MSN Messenger, and YM friends list. It automatically determines where you are located and also shows you other Meetro users near you - a fun way to know if any of your friends are within your vicinity.

Now, Mac users can see what Windows users have been enjoying for the past months. Create personalized groups and custom profile pages and photos with this location-based service.

Registration is simple and the download only takes up around 3MB of space. Visit the Meetro site to sign-up and see what you think of their service.
