This isn't possible - the unit has no writable NVRAM. Actually, it has flash, but the chips used vary between builds and so we never wrote a driver to write to them - the page size (etc) varies a lot between manufacturers.
The ARMGR software does not need to DHCP serve - you just turn off "autoconfiguration on this adaptor" (or something like that). It does local subnet broadcasts to find the music/software server, falling back to all net broadcast if the subnet one fails.
It'll work fine in office environments, we did a lot of testing with this.
