I believe you can do it, you just have to background the tasks you 
want to do in parallel using the ampersand.  So you might do 
something like

   hart at laptop$ at 8am
   at> recording-program &
   at> recording-program &
   at> [control+D to quit]

to have it enqueue both jobs to trigger at 8am.

Selenium is used for driving a web browser in a recorded/repeatable 
fashion.  It might be feasible to use/abuse it for such purposes if 
the website doesn't offer a direct download link you can use. 
However, if it does, using "wget", "curl" or possibly "nc" (netcat) 
might be a better option for downloading a stream from a website. 
If the website offers the feed via RSS instead of live-streaming for 
the programming you desire, you'd be far better off just using a 
pod-catcher like "hpodder" to snag it all with minimal fuss.
