This seems very unreliable, slow, and hacky.  When I login to my e-mail
the system typically tells me the last time I logged in [at least to
that app].  Doesn't the meta-data in the IMAP server 'know' this
information?

The underlying authentication system [PAM via lastlog, etc...] might
also have this information.  If your authentication system is LDAP then
the DSA might know this as well.
