Marketpress Chained Payments Modification

Hey guys,

I wrote a new shipping plugin i needed for the nature of my site. This shipping plugin calculates a shipping cost based on a few factors (size, weight, etc etc) for each individual variation within a product.

The last thing I need to do with this shipping method is modify the chained payments payment splitting to send this calculated shipping cost to one account, and the rest of the total cost to another account.

I havent looked at the code yet, I figured I would check in with you guys for any tips before I dive into things.

So, any tips?
