We all dread needing to change the web site that hosts our update and support pages for an application.
I suggest that it would be useful if the dcupdate.xml file included in a standard way, a url for the support directory.
Further, that when dcUpdater reads the file and finds the 'new' entities, that it updates the application's .dcupdate file for the new url for all such entities that do not match so that dcUpdater can automatically adjust to the new site. This would be most effective if dcUpdater was launched automatically on each boot, or periodically so the new site was likely to be captured before the old site shuts down.
Do you understand what I mean?
