This plugin should be updated, cleaned-up (a lot) and released into the SVN for others to see.

It’s very easy to apply filters to the signature just like the post text, smiles, auto-close tags and a whole bunch of other tweaks and security could be easily added.

I believe it’s also possible to auto-add the signature field into the profile edit page via actions/filters so no user editing required.

Last but not least I think there should be an option that is on by default to only show one signature for the member per page so it doesn’t get too annoying for viewers.
