SMS to video monitor

I am trying to figure out a way to allow employees to send text
messages and have those messages appear on TV's throughout the
facility.

The route I am following involves converting those text messages to
e-mails, creating a script that retrieves those text messages and puts
them in a database on a single PC. Another script then takes the
entries in that database, and exports those text messages through the
s-video port on the PC, cycling through each database entry every 5
seconds or so.

PLEASE tell me there is an easier way to achieve this, whether it be a
completely different approach or just a simple piece of software.

Thanks,
JEFF
