When a customer is filling out the customer details to place and pay for an order could the Order Profile Page be expanded to include a check box option for a text area for delivery instructions.
 
FYI I have done this by hijacking the existing {company_details} field and sending this to the admin email but it would be good if it could be added properly.

Ned, I have done this:
 
Administration > Order Profile Page Settings
and click 'Add New Custom Field'
 
I have also added a filed with a drop down list to ask where they heard about us.

Many thanks Christoper. I didnt see the wood for the trees and you can reference the information as it now appears as a {field_xx} tag in the email options so you can customise the admin message.
