When I use WakeOnLan to scan our household Airport LAN, which includes 
two daisy-chained Airport base stations, 2 or 3 networked printers, and  
4 to 6 periodically varying users, some of them with multiple devices, I 
typically see from 12 to 15 or more devices, 3 or 4 of them with only a 
question mark for a name.

If I track down the identify of one of these devices by re-scanning with 
it turned on and off or by finding out its MAC address, and type a name 
for it into the Name field, does this name "stick" through multiple 
future WakeOnLan scans -- even if that device is off the air for a 
number of those scans, then comes back online?

Is there a difference between just clicking the Name field and typing in 
a new name, and using the "Add" or "Edit" menu commands?

What happens if the device later acquires an internal name different 
from what I've typed into the name field?

Does WakeOnLan keep a permanent cache of all the MAC addresses it's ever 
seen, such that it can identify a device that's been off line for a long 
time and then comes back onto the LAN?  Can that cache be edited?

And finally, can an iTouch be given a name (i.e., have a name entered 
into one of its internal settings) so that it will deliver this name to 
WakeOnLan in the same way that a Mac computer does?

[None of these queries are of great importance; we're just trying to 
keep an eye now and then on who and what is using our LAN.  Is there 
perchance a better -- but still simple -- tool for doing this?
