You've scheduled a meeting with a client or co-worker who's all the way across town. Where can you meet that doesn't take either of you too far out of the way? A.placebetween.us, a Google Maps mashup, helps you find the perfect location. Start by entering your address, city, or ZIP code, then clicking the Add button. Do the same for the other person(s). Then type in the kind of place you're looking for: a coffee shop, a Chinese restaurant, a Fedex Kinko's, etc. In an instant, a.placebetween.us will show you all the matching spots between the specified locations. Click any of the markers to see the spot's address and phone number and get driving directions. Brilliant!
