There are reasons you might want to use a separate application for this. For one, all cell phone numbers that are received, are logged and it gives you an opportunity to return text messages to those numbers. You could use this to provide advertising for the club or perhaps information on your next gig. This is automated by our software. In addition we also allow voting, scrolling text, and other things.
We also provide an internet link for all the above. At some point in the future we would like to offer this as a service. You can check out some of the features at this live demonstration where you can send text messages and vote. Check it out here:

If you want to keep things really simple and don't care about the above, you can use an RSS feed such as a twitter account as demonstrated by the rss.swf sample provided by Resolume. Note that rss.swf is more of a sample than anything else. In reality you are going to need to poll the RSS address to get the most recent post. This will require some changes. Also if you want a different display than rss.swf provides, then of course that needs to be handled. You might want smiley faces etc.

We are working on an interface for Resolume at present.
