This site lets you provide a single html link that will let users download your applications whether they are on their Android Device, or on their PC.
If they are using their phone, they'll get redirected invisibly to the Android Market.
If they are on their computer, then we offer to send them an email which contains a link that they can click on from within their Android device.
Try it out with this link. Download VLC Remote
