you forgot:

3) the network path between the ident-client and ident-server is
secure against active attacks (i.e., no single-user machines; no unix
systems with known security holes, etc.)

BTW, there are also some privacy implications of ident which I really
don't like...  Consider that ad.doubleclick.net could use ident
queries to identify the origin of requests which came in without
cookies..
