Well it was harder than it should have been and this may not be the best way, but here's the code to do it in xcart 3.3.1.
You will need to modify the following files:
customer/products.php
skindirectory/customer/main/products.tpl
And you'll need to create the following file:
skindirectory/Modules/Product_Options/customer_options_productspage.tpl
I am pasting the code below with no warranty whatsoever. I have left extensive comments in the customer_options_productspage.tpl where certain functionality remains unfinished because I don't need it yet. It is also there to give other programmers a possible starting point for finishing this script.
Note: among the unimplemented functionality is price modification based on chosen options. In other words, if you have options that modify the price of your product, this code will not work as is. Othewise, you should be okay using this code, but I don't guarantee it.
Here's the code:
customer/products.php
Code:

The above code really needs some cleaning up and there's still some code in there for my own custom mods that you may not have. I'll come back later and clean it up if anyone wants me to.
Enjoy.
