Hello, here are the promised lecture slides the talk on tracking: http://janoc.rd-h.com/files/doc/pres/lecture-tracking.pdf
Unfortunately the free hosting at Byethost.com started to go downhill towards unusable (slow, way too much functionality blocked resulting in broken scripts, unreliable/buggy uploads, …), so I have bitten the bullet and paid for commercial hosting instead. http://janoc.rd-h.com/ is now the authoritative source for things such as libndofdev and my other software.
My contract with Aalborg University has ended on 31.1.2010 and I have left Denmark. Right now I am residing in France, in Compiègne, working for a small company Reviatech SAS.
