From: "J. Bruce Fields" <bfields@redhat.com>

Add ip address, full client-provided identifier, and minor version.
There's much more that could possibly be useful but this is a start.

As with open owners, client identifiers are opaque binary data, but some
client happen to include some useful information in ascii.
