A new module idea - having seen that the Eventide Timefactor pedal has an expression input 
(as do many other descent effect boxes), I think it would be ace to have a module that was 
tailored to convert control voltages to a suitable resistance to control an expression pedal.

This module would have to work to produce a resistance from a control voltage that could 
potentially be negative (like an LFO) to control the whole range of the expression input. 
Another useful addition would be a voltage controlled switch to control effect on/off or other 
settings.

If theres another method of doing this which is currently available I'd love to hear about it!

assuming you mean to replace the expression pedal...

not sure what you mean, but there is no such thing as negative resistance - an expression 
pedal goes from 0 ohms to whatever its maximum is.

nice idea. the problem with most modern pedals though, is that the switch is electronic - 
you close the contact once to turn it on, and close it again to turn it off. so sequencing this 
on and off may be a little counterintuitive. however, back to the point, you can do this in a 
number of ways. you could use the a150 voltage controlled switch with one input shorted 
and one simply unconnected (haven't got one here, so that's open to correction).
