Standalone XPCOM ?

Im looking at component models and have a few questions about XPCOM.

1. Is there any mature - generic remote XPCOM system equivelent to DCOM?
2. If I install XPCOM standalone and register my components with it, can 
I then install Mozilla and use those components from mozilla?
3. Can I us XPInstall with standalone XPCOM

Im guessing that if I create myself a simple binary distro of standalone 
XPCOM and PyXPCOM, then make all my components install themselves with 
that instance.  When I later install Mozilla I take it I wont be able to 
use my components from Mozilla (JS).
