Does iProd (tablet?) Ethernet interface hint at 3G and tethering?

Tucked away in the iProd product UBDeviceConfiguration.plist file, we see information that seems to imply that this product is going to have an USB-Ethernet interface from the following string:

<string>standardMuxPTPEthernet</string>

The iPod Touch doesn’t have the same Ethernet string in their USB configuration file.  They have this (and so did the original prototype iProd):

<string>standardMuxPTP</string>

Does this Ethernet reference mean iPhones and the new iProd are going to have the ability to plug into an Ethernet wall jack?  Technically…sort of.  It is a USB to Ethernet interface similar to the MacBook Air’s 10/100 USB-Ethernet adapter. 

However, the purpose of this Ethernet interface for Apple in the iPhone is the wired USB tether (that AT&T still doesn’t support but you can enable here).  The iPod touch doesn’t have this Ethernet interface because it doesn’t need to tether.  It, like the iPhone, has a separate interface for its Wifi connection.

So I think it is logically safe to conclude that this "iProd" is also going to have the ability to do the same wired USB tether, making 3G Internet access a necessity.  The only other reasonable alternative is that you’ll be able to use the iPhone to tether to this device.  (Unless Apple’s plan is to have a wired tablet experience?)

We are hopeful that Apple allows its users to have a choice between carriers perhaps using something like Qualcomm’s Gobi 3G Chipset.
