It's very likely I have a solution for this. Still interested?
Combine the info at this link:http://www.digitalbuz.com/2010/02/04/joomla-vtiger-crm-integration-using-chronoforms/With the following information from vTiger/me:Secure posting of form from CF CURL to vTiger needs the following:
1. Check your variable ]
$application_unique_key under the vTiger CRM root directory file: config.inc.php
2. Add
appKey=youruniqueapplicationhere to the CF CURL Extra field (see point 7 in the link above) on a new row
3. Activate the security by setting vTiger WebForms config file correctly:
$enableAppKeyValidation = true (this is set by default but please check...)
These infobits together form the solution you're looking for. Somehow both CF and vTiger failed to mention the need for the "appkey" when posting... many seems to just switch off this security and posting unsecure. (only found one note on this after hours searching...)
I recommend to post securely, especially if you set this in a client environment.

(PS there are issues with CF CURL posting and Arrays (One filed - multiple values) I will address this in another posting)
