[squid-users] Authentication FAQ?

I have been looking through the FAQ and the mailing list to try to
understand which auth scheme might work best for us. In doing this, I
thought it might be useful for some of the more knowledgable members of the
group to compile a sort of grid for a FAQ entry (23.0? 23.1.1?) that
included something of the advantages (encrypted, supported by all browsers,
etc), disadvantages (another password file, not HTTP compliant, etc), the
configure switches needed, and any prerequisites (ident - server on each
client, etc) similar to the following:

auth scheme - advantages - disadvantages - configure switches -
prerequisites

ident
winbind
Radius
NTLM
basic
LDAP
digest
MSNT
SMB
NCSA
PAM
Others?

I could even try to compile the information comparing the different schemes
if those with greater knowledge than me could feed me the information.

Would it be a good idea?
