[Zope] Zope vs. Apple's WebObjects

Hi all A friend of mine knows Apple's WebOjects and Enterprise Object framework quite well and is quite impressed with it. He wants to know if there is a "nutshell" comparison between this product and Zope and how they compare (apart obviously from the eh, slight price difference!). Any pointers or comments will be greatly appreciated! Etienne Tel: (012) 348 4586 Cel: 082 442 8981 Fax: (012) 361 8355
