From time to time a request comes in for a modification to a built-in Integration Server service which makes sense, but would break backward compatibility or a simple service that is useful, but not appropriate for addition to the WmPublic package.
A new solution is the ExtraUtilities Package.
Currently, just a single service from a recent Advantage Forum request, this package can become a repository for distributing additional services to add value to your Integration Server project.
Also, checkout the other cool stuff on the Best Practices > Utilities and Samples page.
Cheers,
