Sure, Windows SharePoint Services Toolkit: Document Library Event
Handler:
http://tinyurl.com/9sxet

This will help a lot. Which do I need to bind my doc  Library
to: SampleEventSinks or the WSS Event Monitor? I'm guessing I could
just bind it to MirrorEventSink.cs, but I've never worked with the doc
library before, or eventsinks, so this is new territory for me. If
you've used this toolkit before, I could use some solid instructions.

Also, in the documentation to bind an event handler to a document
library, it says...

1. Browse to the default view for the document  library.

2. Click Modify Settings and Columns. In General Settings, click
Change Advanced Settings.

3. Enter the event handler Assembly, Class, and Properties for
the event sink you want to bind. For the values to use corresponding
to each sample event sink, see the following section, "Sample Event
Binding Data."

4. Click OK.

Step two does not give me the choice to "Change Advanced Settings."
My choices are:

Change general settings
Save document library  as template
Change permissions for this document library
Delete this document library
Select a portal area for this document library

Does anyone else not see "Change Advanced Settings" as an option?

You will need to fully qualify the assembly name like:
myEventSink, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=xxxxxxxxxxxxxxxxxxxxx

You will specify the Namespace.Classname for the Type name

You can optionally specify some properties to pass in as parameters to
your event sink.

You have to enable it in the General Setting for the Virtual Server in
SharePoint Central Administration.
