Second Life on an iPhone
At first glance, this looks like Second Liferunning on an iPhone, but this is not the case. Instead, it's more of a SL-by-proxy sort of situation, where commands being entered through the iPhone interface are transmitted to an actual SL session running somewhere. There is a slight lag to the proceedings, which any resident of SL will be well familiar with.
Is this tech demo interesting in anything more than an academic way? If you could access SL through an iPhone remotely like this, would it be worth it? What if you could run World of Warcraft like this somehow -- would you? At what point is going mobile more trouble than it's worth?
