We certainly have some problems on initial startup, but it all
normalizes after a few minutes and a handful of retries. Conserver's
ability to say "you've retried too many times, I'm suspending you for a
few minutes" is critical in all of this.

So it's not a situation that's unmanagable at the moment, but it's
certainly not optimal.

Of course, at the moment we have 5 cyclades, but are looking to have 48
very soon, which if I didn't split up my conserver boxes would be 2304
ssh sessions from a single box, which is ... not good. ;)

I think your solution is very elegant and I'd love to see that ability
in cyclades and conserver...
