Unfortunately this is not easily implemented due to Apple's 'walled garden' philosophy. The necessary directories are not visible programatically through iTunes, which is why using iPhone Explorer is necessary.
If a means of accessing the 3rd party directories in the iDevice becomes available, I will discuss with Kovid how we might implement sideloading. In the meantime, the only option is the manual approach.
