with-random-typeout

I have an interface similar to the Editor with a Text and Output tabs. 
I want to use with-random-typeout to print output in the collector-pane 
of the output tab. This all works fine as long as the collector-pane 
does not have an echo-area (:echo-area nil). The problem with this is 
that many commands to be executed in the collector pane need the echo 
area (and generate an error without one). But if it has an echo area, a 
new typeout window is created rather than using the existing output 
tab. I assume this is because the collector pane is no longer a direct 
child of the switchable layout. Is there a way to make this work?

Thanks,
