The Chromium Updater executable can be downloaded
Let me know if there are problems with it, and also if it works.
The Chromium Updater is simple; it does less than the original. It downloads the latest build from the snapshot channel and installs it. It has to be run manually (it probably can be started from the Startup folder) and the update has to be started manually as well. The registry setting created by Martin Endres' Chromium Updater is reused (or created if you have not used it before). I have tested it on Windows7 (64bit).
I plan to make the source accessible, I have not yet decided how and where. I like to (slowly) add more functionality, like a configurable channel address. Comments on both are very welcome.
Update 24. July, 2011:
I fixed two bugs, one causing a crash when accessing the registry, another causing the Chromium download to fail. Also, I removed the requirement of .Net 4.0; now only 3.5 is needed, which comes with Windows7 by default.
Update 3. August, 2011:
A new version of the Chromium Updater is available, which allows to install Chromium from different (configurable) channels. Currently three channels are available, Snapshot, Webkit-Snapshot and Continuous channel.
