You are talking currently very HTML form centric. What if the data is
loaded via some RPC (eg AJAX, SOAP, XML-RPC) or the CLI (eg a file data
import script)?

At what point are strings coming from a form converted to the model's
data types? *

* I have some bad experience with NuSOAP. When I create a WSDL that
expects an integer value it converts the input data with PHP's
functions. This means the input "123abc" becomes 123. Argh! Type
checking of numbers must be done with a regexp manually before
converting the value to int/float.
