Good point! This where the value of Issuer Alternative Name would come 
into play. Basically, the Cert issuer's WebID goes in there and it then

In the meantime, our signer's cert is available from: 
https://www.dropbox.com/s/uig83k71kym398f/OpenLink%20Local%20CA%20Cert.crt .

No, right now you need to be able to de-reference its form a URL.
