[Twisted-Python] Components

[developer at csrules.dyndns.org]

I'm new to twisted. So just jump up and slap me if necessary.
But i'm reading the new "book" (all hail moshez) and
reading about PB. Now micro$oft has alot of information
out there about writing component based appliations
whereby you expose your business object through COM.
Would PB be considered a competing technology for this?
Could i wrap my business objects with PB and expose them
this way?
