Leaving a field "unlocked" in closed sales order

Hello,

I have a very simple customization, a textbox, in SO Entry form that is linked to a character field in the SQL database. When a SO is closed, all elements in the form are greyed out. Is it possible to allow a single field to remain editable (in this case the textbox) even after the SO has been closed? and if so, I imagine something special will have to be done in order to save the contents of the edited field.

Thanks,
Kunal
