I don't know, but when doing updates, it's a case of downloading a file from BBS and then opening it not from the computer but directly from the Nanocom which is connected to the computer by a USB cable. I think it's fair to say that the computer just acts as a store and an internet connection, nothing more.
Maybe a quick email to BBS will confirm it for you. But I think it might be a challenge no matter which device you opt for.
Cheers
