MeetWays.com provides a very simple solution to this problem. Simply type in both of your addresses and the type of place you'd like to meet (Japanese Restaurant, Starbucks, etc) press the "Get halfway location" button and in no time at all you'll have a google maps search result of all the starbucks near the exact halfway mark between you and you're lunch-date.
Examples of where this might be useful:
- Find a meeting place for you and your rehearsal partner.
- Discover new restaurants or bars with a friend.
- Reduce the hidden power-dynamic found in friendships where one person does more driving than the other.
- Find the most convenient seedy-hotel for you and your Craigslist Casual Encounter.
Now if only they had a means of finding a mutually agreeable time we'd really be cooking with gas.
Edit (3/22/2009):
MeetInbetweenUs and aPlaceBetweenUs both provide a similar tool for finding a meeting point except they allow for more than two addresses to be entered.
