I just set this challenge on IRC... I've "encoded" a message and kudos goes to the first person who can tell me what the source text is and how I reached this "encoded" message:
C ,rbe.p ,day ydco y.qy ,rgne nrrt nct. cu C ,.p. gocbi a Ekrpat T.fxrapev C-m oguu.pcbi uprm POC abe ydcbt Ekrpat mcidy x. yd. orngycrb!
Without wanting to give the game away, I've decoded it, and now ROT13'd my solution to avoid spoilers for those inclined to try.

To, er, decode my decoding, just run tr 'a-zA-Z' 'm-za-nM-ZA-N' on a unixy box and paste it in.
I would just like to thank you for a fascinating morning of Perl hackery, textual analysis and ultimately, revelation.

I think you got the tr parameters the wrong way round. But yes, well done! :-)
Kudos to you, sir.

Why yes, so I did :) tr 'm-za-nM-ZA-N' 'a-zA-Z' it is then. Yay for the kudos!
