I am currently learning hb++ (doesnt seem too different from visual basic which I have experience with). I have not gone deep enough to see how hard it would be to write this application.

Basically it would "ping" your bluetooth enabled computer every so often, and once it does not respond (I.E. your leaving the house/office) it will remind you of things - like "Dont forget to take back that movie" or something.

Does that sound useful? The only problem is I don't exactly know how I would do it. Could I do it without a desktop server application? Any ideas would be helpful.
