This can not be done on a per site basis since we already have org X 
and org Y sharing site with relative URL's ~X and ~Y.

Additionally we have the issue that org X might have two forms. One is
published as intended for a purpose that is acceptable but the other
publically posted as used for mailing lists or some unwanted purpose.

This would lead to considering URL level ACL's.

The issue of how a forms purpose could change between visits by
a user is a sticky one. There is no way that an automatic mechanism
could detect such a change.

Agreed - but a logical grouping could facilitiate the user. If the
user has to manage each datum's permisions then the chore might be
too unwelcomed and hence unused. If a user could set *.Personal.* 
as private with the exceptions of URL's X,Y and Z then any newly
define personal field is already permissioned. Also to allow an
URL W to be filled with personal information one need add it only
