problem with retrieving public key

[Andrew]

Hello, 

I'm trying to install gpio-admin using your guide at http://quick2wire.com/articles/how-to-add-quick2wire-as-a-raspbian-software-source/

I get to step three, but the command "curl -L https://q2wi.re/swkey | sudo apt-key add -" never returns. 

Going to the URL for the public key just hangs in a browser as well. 

Any ideas for a fix? 

thanks
