I think you can achieve what you want if you use the Import as URL option in the CSV import dialog:
When you import your CSV, reference this as a URL, for example on your web server, or alternatively in a service like Google Fusion Tables, which has an API for referercing a table as a CSV file. Whenever your map is opened, the CSV will be read and the data re-imported each time, so if you update the source data with your new URL for the hyperlink, this should mean everyone gets the latest data when they open the map.
I got as far as creating and importing the CSV file, but how can I get the "Link" value to act like a hyperlink, rather than just text, so that the map user can click on it to link to an associated web page? See the attachment for a screen shot of my file.

You can configure the CSV after you have added it to your map, to change how the popup window is displayed. In the Layers panel on the right, click the arrow next to your imported layer to go to the Layer Details panel, then click Configure under Pop-ups. Choose the Custom option for Description, then click the Link button, and click the blue plus button to choose the name of the field that contains the link information as the URL of the link, and then enter whatever you want for the Text of the link.
This help topic should cover what you need to know:
When you re-open the map, although the underlying data will be re-imported, the popup window will remain how you configured it when you saved the map.
That's it! Thanks! I was thrown when I clicked the Custom button and didn't see my fields until I realized I had to add them manually with the blue cross. (Also discovered I need to remember to include the http:// in front of the www. in my link.:rolleyes:) Thanks again.
