I sugggest the company contact Oracle or SAP to see if their ERP-suite offers suitable world-wide integration capabilities.

Or else hire somebody that can make a world-wide-web application using a centralised database and decentralised access. Something like amazon.com or eBay have, for example (you don't really discuss the nature of the data in Excel, so maybe I'm thinking on too grand a scale, but you get the idea). Of course, using Microsoft .net one can implement a nice integration with Office 2003.


Hope this helps.
