        That would be the ideal solution, but unfortunately it's not an option for
non-technical reasons (politics, marketing, that stuff). Anyway, I think that
the real number of simultaneous connections won't be so high, and that a
fraction of the ~5000 (I'll try 1000) will do. I've not seen spikes higher
than that yet, and it's not 100% likely that they'll grow much more than
