You might remember a recent obfuscated Monad script that Adam wrote. It's impressive, but not as obfuscated as this one!
This turned up in a search I was doing -- feed2podcast.com looks like an interesting idea. Thank goodness they don't index the comments, because the spam sure is piling high there, Adam :)
[Edit: Monad has now been renamed to Windows PowerShell. This script or discussion may require slight adjustments before it applies directly to newer builds.]
