Just letting you all know - I am making regular mention of K2 blackpoint at the moment in my technical blog;
Recent post covers a real world 3 server installation of K2 blackpoint...

It's probably worth mentioning that I have a lot of blackpoint work coming up, so will invariably be posting all manner of tricks and tips I learn along the way (like the workaround to do client events using SharePoint integration - again, see the blog)
