Do you think there is any way to interface the imp with an Ethernet adapter to get internet connection from a hard line? Maybe make the imp see if the connection is available via Ethernet and disable wifi. This could be useful for imps that will be stuck somewhere for awhile where a hard line is available and not having to worry about power for wifi broadcast. I have an application for an imp where a hard line connection would be preferred over wifi. Just a quick thought, maybe something easy for you guys (and girls) at Electric Imp.
