Big Title. Hopefully little problem.

We are a distributor for a range of products in Australia. We are only allowed to sell those products to AUstralia and New Zealand. However we do have a few other products on our website which we can sell anywhere.

I am wondering if we can put restriction on a per product per zone.

Also we would like to redirect some of our international customers to our licensor in the US.

We do not want to provide a permanent link as we do not want to highlight the current price differences (something we are working on) between the US an Aus. However could we right code that would detect the customer is external of Aus & NZ and them only show them a link if that is true. We do not just want to redirect them because we can imagine that some OS based customer may buy other products or at least like the content of our site.

Thanks
