Is there a way to have the output of the minibuffer and echo
area only display on the current tty frame that I'm on like in
a gnuclient frame under X?
No. Minibuffer/echo area output is displayed on the selected
frame on each device. There is only one selected frame per X
device so you see output in only one frame there. If you had
frames open on two different X devices you would see echo area
output on one frame on each device.
Since gnuclient -nw creates a new TTY device each invocation, you
will see minibuffer contents echoed in the selected TTY frame on
each device.
