[ic] Build-to-Order

[pearless@paradise.net.nz]

Hi,

Has anyone used Interchange for products that need to be Built-To-Order 
where you have various rules as to how the products inter-relate and what 
is required to produce a solution for a customer.

A good example would be a customer using a pick-and-mix approach to 
design their own computer (select a case, then a motherboard, then how 
many RAM slots are there what type and speed of RAM, etc etc) that is 
then build and delivered.

I have seen some JAVAScript based drop down list boxes, but they are 
*very* crude and do not enforce any real rule checking, etc.

Or alternatively has anyone seen an open source solution that is 
available that I could interface to Interchange?

Cheers
Douglas
