How secure is the addin source code?

The source code in an addin is poorly protected against users that are determined to take a look at it. There are both (almost) free tools and commercial tools available that can "decompile" the addins (for all Office-applications). If you need one you only have to search the Internet. Maybe the source code protection is more reliable in the COM Add-Ins used by Office 2000?
