First thing you say to yourself after a compromise is "trust nothing".
Things like idents can/will/should/are targets.

This is changing. In the face of ${BIGNUM} Windoze boxes giving ident
answers like "HAX0r", there is little point, except for the administrator
of the box _giving_ the ident. If that was me, it would be _low_ on my
list.

Small set of people. Much larger set of dupes who would believe/trust
this.

As long as the documentation is _clear_ that this is not a front-line
security tool, but rather a thing to marginally augment logs with
user-supplied info, then I'll buy it.
