MAC Address Change
Enhancement Request: In the unlikely event that a MATE3 should fail and need to be replaced, there should be a mechanism for editing the MAC address within OPTICS RE and keeping the old history associated with the new replacement MATE3.
I can see at least five possible ways to implement this:
1. By OPTICS staff allowing multiple MAC addresses to be supported, or by OPTICS staff changing the MAC address on record whenever a device is replaced in the field.
2. At the OPTICS end allowing the MAC address to be editable there, with some verification that it is not a duplicate of someone else's already existing MAC address (probably easiest and most flexible approach)
3. In the field remotely via secure internet update by Outback staff if it or the software that reads it is stored in flash memory.
4. In the field, with a firmware update to allow the MAC address to be editable by the user there. This is similar to what a lot of internet routers do. Although the other may seem more secure, I wouldn't place my security on the fact that the MAC address can't be changed because that can be spoofed by different equipment such as a hacker's (or by virus software, their victim's) PC anyway.
5. MAC address translation by some device or software layer in the middle.
With that in mind, I'd say either approach is reasonable. If I were on your software team and familiar with it I could probably do it in a few minutes if the software is well designed and managed, plus regression testing however long that takes - if it's automated, maybe less than a day. However that's all up to your management and software priorities.

This idea may also allow use of a wider set of ethernet to wifi adapters, as it would allow the Mate3 to use the same MAC address as the adapter, thus possibly overcoming some router's DHCP limitations.
