Mobui and Viacom-owned VH1 are partnering to offer a social chatroom-like messaging program for AT&T's phones. The program, dubbed "VH1 Watch and Discuss Live Chat" lets users chat in real time together, ostensibly to discuss one of VH1's television programs while the group all watches it. The software is available on around forty AT&T phones now, including BlackJack and RAZR models, costing either a one-time $8 charge or a recurring monthly $3 rate. Mobui says it has plans to offer the app on additional phones, including the iPhone, and expand beyond AT&T, hoping to support over 100 handsets on various carriers.

For those of you who text message, is this a kind of service you'd be interested in? Not necessarily VH1-centric, perhaps, but would you want to mobile text chat with a small group of strangers about a specific topic, sports team, or another TV show? If so, how does Mobui's pricing sound to you? Let us know in the comments below.
