Global Purchasing org

Question

Hello Gurus,
I am working on a Global implementation. I would like to know the factors to be considered in setting up Purchasing orgs for each region. it is fine when each country does their own procurement but the problem is when one country wants to procure for the other country. How can i acheive this.
What are the currency issues involved when there is a cross country purchase.
Will setting up a reference Purchasing Org help in anyway.
Any help will be greatly appreciated.
Thanks in advance
