Actually, I like it; it's quite elegant.  The only problem I see for
using it to host third-party websites is keeping both servers mirror

who decide to use this high-availability solution know in advance that
you only guarantee updates at a certain time each day.

These two steps would be a real pain to hosters using the Cobalt gui.

But I do like it; it's a good solution.
