One solution could be to essentially implement a daisy-chained local serial topology of Arduinos. One of these at the 'front' of the chain would expose its USB CDC interface. Then you'd wire a pair of pins configured for SoftwareSerial to the next Arduino's Serial pins (D0/D1) and so forth. Then you could echo the serial traffic received up and down the chain as necessary, with every member of the chain deciding whether it should respond as appropriate.
