In many business applications, input fields need to be created that perform simple 
validation at the character level, i.e. fields that accept numeric characters only,
alphabetic characters, etc.  Some fields may convert the input to uppercase or 
even have 'fancy' validations for date fields.
With NeWS, these fields can be created by subclassing the server definition of
an input field and have the above mentioned validation occur *entirely* in the server.
With X, each character entered would have to be given to the client app, which
would then take an appropriate action, possibly requiring a round trip. This is awful on
a thin wire connection.
