Filter product features by module

[jave.web]

I need to filter product features in my module (smarty features variable that is later used in product.tpl), note that I don't need to fetch them, that is done by *->getFrontFeatures(LANG_ID)* 

 

I really just need to filter their output - how would I do that? 

 

Is there a way how to get&alter smarty variable in product page in my module? (That would do it...)

 

Thanks.
