The most obvious problem with ISON is that it is not a solid body but likely an aggregate mix of hailstones and gravel. The projected course takes it under the Roche limit distance at perihelion. Meaning my opinion is that it has a very good chance of breaking up into buckshot of unknown size and scattered along its exit vector.

I found these videos that have very good information from the Deep Impact Discovery Mission to Comet Tempel 1 and I thought they might be worth our time.
