@Allinvain - Bitcoins are apparently very traceble. Check this out....
This article has some very interesting information.

"Donald Norman, the co-founder of a London-based consultancy that serves Bitcoin exchanges, said that a data file existed which reflected the complete history of Bitcoin transactions, so that "the ownership of every single coin is completely known and traceable."
I hope that someone still has this data file and is continually expanding it.
