It looks like CheckCommandAccess doesn't work for RegConsoleCmd's either.
Here's something that should work (it should allow you to override sm_trailme).

Hey strontiumdog, if you're still around, in all your plugins can you replace RegConsoleCmd with RegAdminCmd(command, callback, 0, description)?
This will allow the server operators to override those commands, so that they can change the admin flag required to use them, as in sm_trailme here.
