Does anyone know if Ripple has a client that can be hosted locally, in case ripple.com disappears?

I got back into BTC when I read about BTC and Ripple in several articles floating around the blogosphere in recent months.  Just in time to have missed out on the possibility of bitcoins that cost ~$10 instead of ~$100.

I first read about BTC before GPU miners became popular.  I was thinking about writing my own when I saw others release the first ones, then I got discouraged when I read my machines (which all have nvidia cards because they're better for gaming) weren't cost-effective.
