How is it done? Is this a BSDI's own invention or there are some existing prototypes of this feature? Any known papers/techreports about "user classes" and their implementation? -- With best regards -- Andrew Stesin. +380 (44) 2760188 +380 (44) 2713457 +380 (44) 2713560 An undocumented feature is a coding error.
