[Elecraft] Can KPA500 Operate Remotely?

[k5aj at gmx.com]

Hi,  Can a KPA500 be operated remotely, for example, in a different room 
from the operator?
Specifically would such remote operations be possible via USB cable or 
additional hardware,
or even via IP using additional hardware on the amplifier side.
The need is to be able to switch remotely between standby and oper.  
Ultimately this might
allow both a flex radio and KPA500 to be separated from the operator.
Thanks very much,
Jack
