You should be able too. I understand that any limitation would be at the raspberry pi side. Just visit the raspberry pi at http://www.raspberrypi.org/ for some research and get back to us on how we can also do this 
If we had access to the Pi itself with the zenMiner software loaded, sure.
Here is the exact quote from the email that I should have just tossed into my last post.
Quote from: Eric
In our effort to maximize quality control and the overall experience of our customers, all zenMiners are setup and configured at the seller's facility and then protected from alteration (root access) to ensure security and reliability. We did not include support for wireless devices because a wired connection to your miner is always going to be more reliable than wireless. I'm sorry if this causes any inconvenience to you.
Thats interesting my zenminer controller sd has the noobs image on it.....I am trying to figure out what I need to do at this point. Any suggestions? So much for plug and play with this.....
oh so even if we had a wireless usb.. we couldn't add it... thats a big drawback....
