Given the fact you still haven't apologized to Intersango and are acting like a spoiled child, I think they should charge you a license for back programming contracting of 5000BTC . If you don't want to pay it, you should pull every line of code that they helped with out of your codebase. It is not up to them to tell you which lines this is, so unless you have specific version-history knowledge of their contributions, they have the legal power to force you to throw out all of your code. You should be gracious for their past help, and apologize for your outrageous acccusations you have made in the past 48 hours.
Intersango seems like they are way nicer than me though, so feel lucky.
I am not sure if this is directed to me. If it is, there is not a single line of code that Bitcoin Consultancy has contributed to witcoin. Again, as I have said elsewhere, the very latest commit to the private repository was June 3rd, 2011, which was before I even participated with Bitcoin Consultancy. And I am uncertain what there is to apologize for relative to Bitcoin Consultancy.

The power of slander and misinformation. =/
Othewise if you meant the message directed to noagendamarket, the codebase is not his. It is practically entirely mine. I say practically because glancing at the repository I see commits also by tcatm as late as February 2011. The rest since then have been entirely my own. Though, I do recall tcatm having helped me with some css later, which I had included in my own commits. But otherwise noagendamarket hasn't contributed any code whatsoever and is not a developer/programmer.
