I saw this project and checked out the examples. It's not a 1 day job. It's about a 15 minute job, plus some polishing in case your page templates have changed from CubeCart defaults.
In fact, it's already done and just needs a quick copy/paste to your page code and it should work both on product listings and detail pages.
If it doesn't work immediately tweaking some 10 lines of code won't take long.
If you have any questions, feel free to send me a message.
