Using Flirc with a non-IR Roku

[IPenrod]

I'm currently using Flirc to interact with my non-IR Roku by mapping custom Global Keyboard Shortcuts in KDE to launch individual bash scripts that submit the corresponding curl command to POST to the Roku's IP address.  While this is working well, I've run in to a snag.

I use the computer and Roku on the same TV with different inputs.  When I lock the KDE desktop to switch to the Roku (which is desired), the bindings stop working.  I'm fairly certain this is because the "locked" status is preventing KDE from initiating the shortcut.  

My question is... Has anyone else found a way to get this, or something like it to work when the desktop is locked?
