Make it easy for people to READ-ONLY my wiki

We have used the "magic URL" to direct people who were "registered members" on our website to access the wiki. We only want to allow read (or comment) access, but no other ability to write. We do not want to have to manage accounts in any other way and do not want to force them to create a PBwiki account that we then have to manage.

How can I do this with 2.0 as there is no "sharing" link or magic URL While I could create a "generic account" and give people the ID / password I want to go directly to the wiki from my web page link - no additional login page.

Suggestions?
