Not sure how far back this goes but as of one of the wix builds in April 2011, there is an attribute called 'MultiInstance' that can be put on components to make the component have a different guid in each transform. So it would look something like this: <Component Id="MyComponent" MultiInstance="yes" Guid="YourGuid">
That fixed our problems with registries and shortcuts not uninstalling correctly with multi instance installs.
