URGENT : Deploying Proxy Objects?

I found the documentation on nsISupport Proxies
(http://www.mozilla.org/projects/xpcom/Proxies.html) very helpful on
what Proxy objects are and how to write them, but I still don't
understand how to deploy them.

On a windows machine, if I put the dll and the typelib (.xpt file) in
the components directory is that sufficient or do I need to do
something more.

Which event queue should I use to get notification of changes
Document's DOM?

Any help would be greatly appreciated.

thanks
Jayant
