Is it possible using goo.gl might get you something like a poor mans CDN? I'm thinking it may possibly respond immediately with cached results.

No, it responds with a redirect:

    $ curl http://goo.gl/OCK7V
    <HTML>
    <HEAD>
    <TITLE>Moved Permanently</TITLE>
    </HEAD>
    <BODY BGCOLOR="#FFFFFF" TEXT="#000000">
    <H1>Moved Permanently</H1>
    The document has moved <A HREF="http://twitter.github.com/hogan.js/1.0.0/hogan.js">here    </A>.
    </BODY>
    </HTML>

Edit: I suppose the headers are more important:

    $ curl -I http://goo.gl/OCK7V
    HTTP/1.1 301 Moved Permanently
    Content-Type: text/html; charset=UTF-8

No. Regardless, a second DNS query will have to be performed by the client when Google responds with the permanent redirect.

Just because nobody explicitly said it - a 301 redirect is actually cacheable per §10.3.2 of RFC 2616. But google doesn't set a long cache duration - another one of your responders posted the response headers, it was 86400s which is 1 day.
