There will be a lot of it. And it will hurt performance too:

level  "acct.c", "auth.c", "builddbm.c", "checkrad.c", "exec.c",
"files.c", "input.c", "pam.c",  "proxy.c", "radius.c", "radiusd.c",
"radutil.c", "request.c", "rewrite.y", "rpp.c", "scheme.c",
"snmpserv.c", "sql.c", "stat.c";

See http://www.gnu.org/software/radius/manual/html_node/radius_23.html#SEC33

Default log prefix displays in logs the information about the request.

It will fall into `category *' settings.

`channel' defines logging channel: will it be a file or syslog facility,
what additional information (pid, category name, etc.) should be
displayed when printing to that channel.

`category' describes where log messages related to a particular category
should go.

checknas.rw contains functions used for checking simultaneous logins.
log-hook.rw contains logging hook functions.

Hmm, that's possible with some modifications. Let me think about
it. I'll write you a bit later.

Yes, it does.

You may remove NAS-IP-Address from the request, using this function:

integer
foo()
{
        delete %[NAS-IP-Address];
}

It should achieve the desired effect.
