IPad Internet access when WiFi and Cellular features are disabled

Question

Local security policies require me to disable all wireless communications on devices operating within specific “Controlled Access” areas.  Is there a specific lightning (cable) adapter I could use to connect an iPad device to a hardwired Ethernet cable (CAT-5 or 6) to facilitate wired internet communications in this situation? Alternately, can I use a standard Lightning-to-USB cable connected to a MacIntosh computer and somehow configure the MacIntosh to act as a router-like device for internet communications between the iPad and other intranet or internet endpoints that the MacIntosh is also able to interact with?  Basically, I need to establish internet connectivity to/from the iPad without the use of wireless communications options, and I'm interested in the options I could pursue.

Thanks for the YouTube links bobseufert. 
I'm going to try this approach out myself (just to verify that it works), but I'm really hoping that another - less encumbered, approach can be found for my end-goal.  The larger-scale view of my need includes connecting multiple iPads (one per workstation area) to a local intranet.  Since I can't use a WiFi or any other wireless communications solution for this installation, I might need a collection of adapter cables and powered USB hubs if I choose to implement the options detailed in these two videos on a large scale.  Sure, that's all possible, but what I'm really hoping to find somewhere is an RJ-45 configured Ethernet-to-Lightning Adapter that will work with iOS devices. 
From one perspective I can see why this type of adapter has not been built yet.  However when you think about the wired adapter options that are available to connect the iPad/iPhone to a remote display (or overhead projector) - there is at least three different versions available through Apple, even through Apple sells wireless video display capabilities (I own two Apple TV devices myself), you wouldn't think that a wired network option for these mobile devices would be something out of the question...   
BTW, I noted that Redpark (www.redpark.com) has some serial (RS-232) adapters for the older 30-pin iPads/iPhones and for the newer Lightning equipped iPads/iPhones that Apple has signed-off on.  Redpark also has an RJ-45 to Lighting Adapter, but this particular implementation is built (i.e., wired) for the CISCO Console port, which is not compatible with your typical CAT-5 / CAT-6 wiring configuration. 
If anyone else finds a Lightning Adapter providing both Ethernet-based Data (via an RJ-45 connector) and Power to keep the iPad devices charged (24/7) I would really like to hear about it...  Thanks for your continued support!
