XPCOM is what powers Mozilla, Netscape, Komodo - This is not a OS fad.
What you describe with HTA, is a lightweight hack in comparison. XPCOM works similarly to COM, but is available on any platform that has a Mozilla port. plXPCOM supports two-way communication - from any mozilla/gecko based application out to perl, and from perl out to any XPCOM component.
