I am looking dropbox.com as an update method for my software which is going to be deployed manually by me among many computers. I am planning to install the software into a drop box folder which can be controlled remotely. So if I place a new version of software into the drop box directory all previous versions of software is automatically updated[this will not replace the old version, a new exe will be deployed without deleting the old version. this will help avoid damages to the requests which are currently processed by the old version exe.].
I am also planning to deploy an dummy application. so any request to the main application will be first received by this dummy application. The dummy application know which version is the latest version and routes the request to the appropriate exe.
Please send your suggestions. Can any one see any disadvantage in this approach?
