21. The apparatus of claim 16, wherein at least one of said plurality of subscriber devices comprises:

means for controlling the operation of said at least one of said plurality of subscriber devices; and

means for storing at least one of program data and configuration data, wherein said storing means is coupled to said controlling means.

22. The apparatus of claim 21, wherein said at least one of said plurality of subscriber devices further comprises:

means for pointing to one of program data and configuration data currently in use at said at least one of said plurality of subscriber devices.

23. The apparatus of claim 16, wherein said at least one of said plurality of subscriber devices further comprises:

means for facilitating communication between said apparatus control means and said subscriber device control means.

24. The apparatus of claim 16, wherein said at least one of said plurality of subscriber devices comprises at least one of:

means for facilitating use of a computer at said at least one of said plurality of subscriber devices; and
