Integrate with Eloqua CRM

Hi all,

Can anyone comment on CRM integration module development? I see there is an existing CRM API module as well as one which integrates with the Loopfuse CRM. We are using Eloqua, which is similar.

I need a group of contact/registration forms to re-post their contents to Eloqua, so folks who enter their information get placed into the CRM for reference. If the forms were straight HTML this would be trivial but I'm not sure how to go about writing a module which would do the form alter hook properly for this purpose. As far as I know all we need to do is add some hidden fields and integrate the re-posting to the Eloqua URL.

Any help would be much appreciated, I'm looking forward to contribute to the Drupal community which has given me so much.

Regards,
-Patrick
