I just got a message from Tim, after asking for a product comparison plugin, that WPMU does not have a "product compare" plugin. This would be a cool idea if WPMU could add such a plugin. Tim directed me to another plugin (pricing tables) but this is not what i was specifically looking for. Basically i wanted to add a comparison table with products and specifications like in the screenshot below but with the power of the WPMU team behind it. Or is there an easier way to get this done?
