I'm not sure how to do this directly, or if this is even possible in 
Ruby, however what you could do is to insert wrapper code into your user 
programs. This code could override existing methods and take over the 
input and output for the user programs. When the programs were then 
waiting for input from the user, they would then call the wrapper code 
and this could then indicate to the rails program that the users Ruby 
program was waiting on input.

hope this helps, matt
