Manchester northwest drupalcamp

I'm in the process of looking for sponsorship and a suitable venue in Manchester for a Drupalcamp. I'm aiming to make it a two day event, but other than that, I'm after some input on the format and content.

So, what would you like to see at your ideal Drupalcamp Manchester? Who would you like to see talk? What topics are you most interested in? Would you prefer to see talks, workshops or a mix of the two? I'm open to ideas, so please fire away and help make Drupalcamp Manchester an event to remember :-)
