A simple approach to this might involve something like:

1. extract module name / 1-liner to a database table, keep it updated from 
time to time

2. periodically query the table for a random row (via PHP)

3. convert the returned record into a formatted string, or XML for delivery 
RSS style

4. use some PHP to access the day's module/desc. and insert it into a small 
container on the main page.

if we have access to PHP / database it is a very simple matter to construct 
these queries. for something this small and specialized a file-based DB like 
sqlite would work just fine. There are several PHP XML libraries for 
constructing XML/RSS - so there wouldn't be a need for wheel-reinventing.
