Here's a potentially fascinating development: a gay couple from Texas get a DC minister to marry them via Skype.
In DC, marriage is legal for gay couples; in Texas it isn't. The couple had to register in DC first, but the ceremony relied on remote technology. It almost certainly won't hold up under Texas law ... and isn't an attempt to challenge the state's ban on marriage equality. But it does reveal the conflict between an institution now so geographically restricted in the US and the technology that is making geography less salient in our everyday lives.
