One of the recruitment agencies (Cambridge something) had a website setup with a FAQ on KAL that I read through a while ago. Do a search and it should show up. I have seen KAL contracts being offered by all the main agencies though - PARC, Rishworth etc.
For what its worth the money was pretty poxy (for an F/O on the 330) but then beggers can't be choosers. I was looking at it as an a*se covering exercise incase my present employer decides to let us go.
