Modifying for variable Products

Hi all,

I was wondering if it is possible to modify the code to allow licensing for variable products. I would like to use this plugin on my site but need to be able to give options like 1 Device License, 5 Devices, etc. and update the price but generate licensed sites based on variable option.

If it can be modified for variable products how do I append the code to include variable products,

Many Thanks
Stephen
