I can envision that the users would want to have an updated version of the
Excel file "Measures 2006-09" and "Measures 2006-10" and would also want to
have an updated file name for the PowerPoint document. Any suggestions on
how that could be achieved. I didn't see anything obvious in the link you
listed.

Create a folder first, move both the Excel and PowerPoint files into the
folder.
Open the Excel file, copy the cells that you want to show in PowerPoint.
Open the PowerPoint file, click Edit > Paste Special.
Select Paste Link.
Save the PowerPoint file.
If you update the content in Excel, you will be prompted to update link in
PowerPoint.
You can change the file name for PowerPoint or have an updated version, but
you can't save the Excel file under a new file name though as it is pointing
to a specific link.
See if others have a solution for this.

I've played around with the EDIT LINKS and attempted to record a macro to see
what was happening, but nothing was recorderd. I'm thinking this will need
to be done with VBA.

Something like this:
Show me the link and let me edit it

Alternatively, you could create your 2005 file and save a copy as MASTER.XLS (or
whatever name you want to give it ... doesn't really matter). Create the links from
MASTER.XLS.
When you want to replace your 2005 data with 2006 data, edit the 2005 file, save it
as 2006, then also save a copy as MASTER.XLS, overwriting the old version of the
same name.
PPT will continue to link to MASTER.XLS, but will now have the new data.
