Fenrix, you forgot one of my favorites: In the Late December, by Greg van Eekhout (from Escape Pod.) Rocket Launcher Rudolph! http://escapepod.org/2007/12/25/ep138-in-the-late-december/
FWIW, I'm pretty sure Pratt and Shaw didn't write "On Dasher." I think that was Jonathan Gillespie :)
Just touched this for the first time in almost four years. What am I still missing from the list?
