Wait, after re-reading Blair's email 2-4 times, I realized what he is suggesting. Correct me if I'm wrong...
I don't need to bother with ARPINSTALLLOCATION at all, instead I should use AppSearch/ComponentSearch at startup (during uninstall/upgrade) for a "well-known" component (mostly one in MYROOTDIR) and somehow (this is where I'm a bit unclear) use the search results to set MYROOTDIR. That sounds like a great idea. I'll need to look into AppSearch/ComponentSearch a bit more to determine how I would leverage it to obtain the currently installed "well-known" component's install directory. Thanks.
