Passing params to ZOHO

It would be extremely useful if it would be possible to pass data to a ZOHO application.
I work with a content mgt. system and I would like to pass some variables from there to ZOHO creator when it starts a form.

Example.
I would like to be able to pass first-name, last-name, personal-id and sex to an application so that the form is already pre-filled with the information I already know about that user.

Would that be possible??? Could It be made possible??

And of course - this would be my next question - could ZOHO pass data back to my CMS system???

Having this ability would make ZOHO creator very usefull for building add ons to existing applications.

best regards,
Frans
