It should be pretty simple to program. It's just a 3 or 4 column CSV file.
I believe Google Maps might also be able to create a custom map with a CSV file upload. Etc. Any other uses you can think of for this? If you are a GPS user, is that something you'd find useful?
I wanted to suggest a feature for Happy Cow and so am posting to see what people thing. I'll be traveling to Europe and plan to use a GPS to find my way around the city since I don't have need of a smart phone to justify their costs. At least for the Garmin GPS it's quite simple to load new points of interest (POIs), like restaurants, etc. Would you find it useful if Happy Cow could download search results into a file that can be loaded onto a Garmin?
