you can create your own form Viewhelper with honeybots included...
it's a very basic implementation but works pretty well

https://github.com/daKmoR/TYPO3-xform/blob/master/Classes/ViewHelpers/FormViewHelper.php

and you may use this validator on your action
https://github.com/daKmoR/TYPO3-xform/blob/master/Classes/Domain/Validator/XformValidator.php

if you have any improvements just let me know...

another idea I had would be to not set the target of the form but set 
something like data-tegrat="<encoded target>" then decode and set the 
"real" target with javascript...
should prevent even more bots (who don't fall for the honeypots) but of 
course it would make javascript a requirement :/

cheers
