Now at&t is sueing Vonage

As if Vonage hasn't spent enough time in court with Verizon and Sprint Nextel now at&t is going to sue them. I'm surprised Vonage is still holding on with there stock price at $2 a share you have to wonder how much longer Vonage will be around. But this really makes you wonder about VoIP, Verizon, Sprint Nextel and AT&T all have patents in this area how can the small players and startups survive. Let me know your thoughts.
