You can use your own product/article hook function for 
getItemMarkerArray. So your fields can be displayed in the frontend for 
a product or article.

And you need to add the name of your extensions to 
GLOBALS['TYPO3_CONF_VARS']['EXTCONF'][TT_PRODUCTS_EXTkey]['prodCategory']
in order that loadTcaAdditions will work correctly.

However many field names are still hardcoded inside of tt_products.

Fields can be added but they are not used in the code. And the 
parameters of hook functions might change in the future.

In December I will move tt_products to PHP5.
