If I may, I'd like to submit this installer for the remaining bounty:

http://media.andarazoroflove.org/Devcoin-Installer.exe

This is a commercial-grade installer, creates shortcuts on the Desktop for Devcoin and has a brief intro to Devcoin in its about dialog.







It has full uninstall support and is built using the Devcoin and devcoind binaries from the official Devcoin site. It also contains a link back to Devcoin. Feedback is appreciated, nearly every item in the installer can be customized and I hear by pledge to maintain the installer upon future releases of the client.
