I think the casual user just wants to browse the HEAD revision and that
is what google provides and makes easy to do since the interface is not
cluttered with a bunch of links that won't be used anyways.  If they want
more than that they are probably not a casual user but a developer and
have an svn client.

Regarding Trac I was able to use it successfully but its a large
complex system and it just took too much of my time investigating
all the numerous features.  I think its better suited to projects larger
than an R package.

By the way, there are some distributed version control systems that
work with svn such as svk that I had intended to investigate at some
point but so far have not found the time.
