Arduino + mdek units possibility

i am asking about the possibility of getting a link between mdek tags and an arduino board through usb cable perhaps … could it be done ? if let’s say we have to receive a message or a variable change from the arduino and get it to the tag to be sent to the rtls web manager ( if we change some things in the code) .
could it be done ? any ideas ?

also how can we publish the web manager to internet cloud (saying network other than the local network as we only can access the content of web manager if the computer is on the same network with the gateway raspberry pi).
