Would there be such a thing as a link that never expires?

basically, I am trying to do all of our site in one LSQL database, and there will only be one section that I'd like to have expiration dates. Is this possible?

Really, all we need is a start date, an expiration date and notification of expiration sent to the link owner. In addition, we'd like to be able to set links to "never expire".

Is this possible with these plugins? Would it be a different plugin? Anyone up for it?
