What we have done is to use two differnet versions of w and ps respectivly.
The original ones has been moved to /etc and can only be used by root or
a special group of people (group staff). The versions that are runnable
by ordinary users doesn't display the arguments only the command. The
modifications are simple (4.2BSD):

In w:

286c286
<			strcpy(doing, lflag ? pr[i].w_args : pr[i].w_comm);
---
> 			strcpy(doing, /*lflag ? pr[i].w_args :*/ pr[i].w_comm);

and in ps.c you let the routine getcmd always return with only
the command name:

	/* if (cflg) { */
		(void) strncpy(cmdbuf, u.u_comm, sizeof (u.u_comm));
		return (savestr(cmdbuf));
	/* } */
