Setting the prototype read only

Dear all,
Having two wiki installations on the same server can cause some trouble
if someone logs in to both wikis at the same time.
Do you agree that I set the prototype into a read only modus, so that
people can access all the content but are not allowed to login for
editing. The current version of the wiki of course stays editable.
Best,
Tom
