Any things to watch out for - using RokMenu for categories navigation

[ouroborus]

Hi,

So on the store I'm building I wanted the categories in a decent looking top menu or sidebar.
That mean switching the categories off from the default.php in the main virtuemart view.
VM 2 also has the Categories module, which can be placed in the template positions but it doesn't have any decent media support(without some hardcore php I guess). So I'm thinking of using a RokMenu or similar for the category navigation. I was thinking of just pointing to the category URLs. I.e ........../index.php/store/hand-tools/powertools/indoortools in each menu or child.
I know this looks very simple and it looks to work fine on the DIY demo store - I'm just wondering if this will bite me later on?

I'm doing this as with more advanced modules like those that come with RocketTheme I can add pictures etc in with the menu, like amazon's 'Shop by department' menu etc.

Cheers,
