This appears to be true on Windows as well.

PM boinccmd on client
On the Mac, BOINC projects are run as user and
group boinc_project, while the BOINC CLient is
run as user and group boinc_master. The
gui_rpc_auth.cfg is readable _only_ by members of
user or group boinc_master.
The sandboxing on the Mac is specifically
designed to isolate project applications from
BOINC itself, in addition to isolating both
project applications and BOINC from the rest of
the files on the computer..
If I understand you correctly, you would
definitely _not_ have access to the RPC password,
I don't know if this is true on Windows.
Cheers,
