Separate Merchant account for some products

I have a client that uses Zen cart to sell products and also trainning. They want to be able split the sales so that payments for trainning go through one merchant account and payments for products go through another merchant account.

The only way I can see how this can be done would be to clone the zen cart and have the two zen carts run from the same database. However, this still leaves me with two questions...

1: Can each zen cart have different categories from the other?. e.g one cart would sell widgets, the other trainning.
2: Could each zen cart have different settings for their merchant accounts?

The important thing is that both zen carts need to utilise the same login details, so that customers can move freely from one zen cart to the other.
This is a little out of the ordinary but I am just wondering if it can be done.

Thanks

This is possible without having two separate stores but requires customized coding.

You would need to test the shopping cart content for product or training and then enable / disable one or the other payment method. The trick is that you can't allow products and training in the same shopping cart. This may require a message to be displayed (you can't have both things in the cart - choose one....) and block the customer from proceeding further until they made a choice.

Thanks Frank,
I am not really a coder, more of a designer with a little coding experience. Is there any sample code out there that i might be able to adapt?

Thanks
