I really like to follow the development of Transmisson so I often download the nightly builds to see what is new. I thought it would be nice if there would be an automatic updater. Transmission uses Sparkle for updates but this is only for the official releases. So I write this applescript updater. Please give me some feedback if it is working for you.

Download: Transmission Nightly Updater

You could also use it do build your own nightly updaters for other applications. Comment on this if build your own.
