Well there are two ways to do this, I connect via firetalk and send my co-host into a mixer and the mixer into computer #2 running mixler. You could use the Spreaker desktop to connect via skype. Use the coupon code sopfree if yuo sign up at spreaker
Just dropped in at the tail end of this, I think. Maybe you already discussed this ... could you talk about best practices when streaming live on Spreaker w/a remote cohost?
