Oh, for the record, E-Prime 1.x could also do something this, coupled 
with a system called IFIS.  To be fair, that required two computers 
connected by ethernet, or (in an earlier version) one computer running 
some specialized server software.  E-Prime handed the data off to the 
server, which then presented it to a separate client program for 
presentation to the experimenter on a second screen.  So in principle, 
yes, with sufficient engineering, E-Prime, coupled with external 
software, can do what you ask.  But I still wonder if it is worth the 
effort.
