Would it always be the same program? if so then the alias would work
well, but would be tedious to create one for every command in the
system.
A fairly simple script that would loop forever could read all input and
then call your program with the input as the arguments. You would have
to trap the ability to break out of the script so they could not get to
an actual shell.
something like
while 1
do
readline <read the command input line>
<put the values read into VARS here>
myprog $VARS <call your program while passing the values read>
<reset VARS here>
done
