Mark,
The.MultiCore version is still 'experimental' because I haven't yet had the chance to port the unit tests. It has all the same functionality as the standard version and. Knowing the changes I had to mak I feel very confident. But feeling confident and seeing the green bar in FlexUnit are 2 different things, thus the current status
I definitely encourage you to spend a little time with it if you have a problem that would best be handled with modules.
However, to see how to package and reuse a utility such as you describe, have a look at the AIR utility called DesktopCitizen and its related demos.
