Pretty much just Splashtop 2 which is free to use over WiFi. To use it from the outside, it has a monthly or yearly fee of about a dollar.

It has either a direct touch to click interface that isn't always accurate, but fun. Otherwise, it just turns the whole screen into a touchpad. You can pop up the extra keys when you need them, for ground targeting.

Actually, you can get a few weeks worth of free "anywhere" access by referring a friend. Then, you both get 1 week of free access. I won't be spamming a referral link, but if anyone is interested in a free week, I can PM them a link.

Googled splashtop and came across this article http://www.pocketables.com/2013/02/5-reasons-i-want-to-move-away-from-splashtop-as-my-remote-computer-app-for-the-ipad.html

Yep, read that. If you can find something that works this well for 3D graphics, I'm all ears.

I was just playing Borderlands 2 from my phone (using a 360 controller, of course ) while in my living room. Almost no lag. I think I will pick up one of those USB to micro "on the go" cables and see if that works through.

I will be interested to see what the latency is like in a WAN setting.
