Sure, not that difficult as to be impossible, but difficult enough so that 
nobody implement it yet.

The question that bothers me, for example, is: do you catch stdout, or stdout 
and stderr? And if you catch both, you need to make sure the forked process 
is not blocked writing to stderr, while jam is blocked reading from stdout.
