I'm not sure if you mean parallel as in "mutualy exclusive" or as in "combinative".

There is a case where a program is looked up by a timestamp with an "at" parameter.
If "current" and "at" parameters are used together, "current" will take precedence over "at" and redirect accordingly to the current program.

I have pondered on solutions like /programs?at=1359000000 and /programs?at=now but am not convinced.

Indeed, if(id == "live") is a pain whereas if(query.current) is much smoother.
