Seems to be tablet only at the moment.
I've played a few rounds now via iPad and it is a useful way to play if it isn't possible to play the real thing. It would be interesting to know what sort of influence it has on the round in progress. You are able to stop cruise missile attacks from the other commander but also get missile kills yourself. Snipers should be easier to spot now and are unlikely to remain hidden. Deploying the gunship doesn't appear to be that effective compared to the missile option.
It is interesting to note that on a full server I've been able to finished a few times around 12th overall with about 7,000 points.
When it first appeared you could use chat but I've not been able to use that the last couple of days for some reason. You can see the in-game chat and take screen shots for evidence should someone be abusive or make other inappropriate comments. I've not tried the voice of god yet... You can also see the scores and potential cheats. Last night someone (roswell85 - see the screen shot) was going 20:0 until they were called out. I suspect the cheat was turned off as they were then very vulnerable and had no kills and soon left the server.
I think it is an interesting gameplay option to have and worth a try if you have a tablet. It seems to work OK but you still get lost connections and funny messages like "browser plug-in needs to be installed" and I have seen a "you need to be running Windows to play this game". I guess it is running HTML rather than a proper app.
