[squid-users] SIP, SIP2, NCIP authentication?

Has anyone configured squid to authenticate using SIP, SIP2, or
NCIP. These are protocols used by library systems and are the bases
for many automated features at libraries. Examples include self
checkout where a patron might run their card and a book through a
scanner.

They aren't complicated protocols. The first two are proprietary ones
designed by 3M years ago. The last the open one designed by NISO (
http://www.niso.org ) who maintains all the formal library Z39
standards.
