There's no reason why you couldn't do this and infer a relationship:

<div class="vcard">
<h2 class="fn org">Foo Co.</h2>

<h3>Member Listing</h3>
<ul class="xoxo">
<li class="vcard"><a href="http://mulettesgalore.com" class="fn url"
rev="founder moderator member">Joe Bob</a></li>
</ul>
</div>

So basically you could contain the member hcards within the group's
"master" hcard... *I think*.

Does that make sense?
