Add-In Version Check

Hello,

I have designed an add-in (which adds a tab to the ribbon) and I'd like to add some functionality to "check for updates." Right now, the only way I can think of doing this is to do the following:

1. Create a .txt file with the version number (e.g., 1.1)
2. Upload the .txt file to a public dropbox link
3. When someone clicks "check for updates," it downloads the .txt file from the public link, reads the .txt file, and compares to the current version.

This will probably work, but I think it'll be a hassle to download a file every time it checks for updates. Is there an easier/faster/simpler way to do this?

Thanks,

Evan
