Passing a cart contents from one website to another, platform independent solution?

I work for a product manufacturer and we do not sell products directly to customers, distribution is through our dealer network. I'd like to p开发者_如何学运维rovide our website visitors with a means to build a shopping cart and then pass the cart contents off to the dealer website of their choice.

The solution needs to be platform independent, even though I will be developing in ASP.net since our dealers' website platforms vary. I would assume most, if not all, do not have an existing API to interface with.

What do you think would be a good means of accomplishing this task?

Thanks!

make a quote registry (with mongodb, memcached or whatever you like) and make a restful api to access that registry you can use any format you like (like json, xml ). You can even use some kind of queue manager to acomplish that
