MarketPress on MU network

Hi Guys,

looking for a bit of direction here please, we would like to be able to display global products from the network on the main blogs homepage in a grid format but the only way we have been able to figure out how to do this is by using gridmarket as the theme for this page. This works fine but the main page now becomes a shop, is there any way do this without it becoming a shop

Also anyone get any network shops working on marketpress, would love to see some examples

Thanks in advance
