Yep, but unless there is a significant breakup and chunks hurled out of the debris field with a lot of velocity, I wouldn't expect much out of the exit - but there is that slight chance. The entry debris might present a better chance of seeing some debris meteors on earth as the entry of ISON crosses the elliptical just inside earth's orbit.
Definitely something to watch...
For a meteor show yes, however what I am speaking to is they speculate the debris will have fragments not even the size of an atom.
This is akin to aerosol....in huge quantities.
Think of it as a few major event volcanoes erupting at the same time and what that debris injection would cause.
