This is a little Mono c# script I wrote to let us know of new media on our media shares.
I schedule it to run once a day with cron on my linux box.
Initially I wanted to work on file dates, but that didn't work out nicely, so now I 
just cache the current day's files and compare that to the previous days.
Works in windows and linux.
