Many thanks indeed to all of you who have replied with all your suggestions and links to your projects (both on and off list)! It looks like there has been some really excellent work already done on this topic and there's lots for me to be looking at here!
We're still at a very early planning stage for this project, so there's plenty of scope for all sorts of different things, so all your advice will be really helpful! I've passed all of your suggestions and messages onto our project leader, who may very well be getting in touch with you to talk more about your experiences!
Thanks again for all of your help though! It really is very much appreciated, and I will try to keep you updated with the outcomes of our project as we progress!
