It looks like we just pick something we want to include in each Twitter message that is searchable, such as the following five letters:

Hey, having a great time here at the SouthPoint. Wish you were here!

Then the folks back home can go to Twitter.com and search for and see all tweets from chippers at the convention even if they don't have them on the list of those they're following.

Now, the next question: Is there free wireless anywhere on the SouthPoint property?
