[Zope] silva and plone-cmf

has anyone done a quick comparison of plone/cmf and silva. I just installed silva and it seems really slick... and performs faster than plone... But looking in the freebsd ports collection it doesn't look like plone has been put in to run with zope 2.7.2 and python 2.3.4 -- so silva looks better all the time. Still, I know a little more about plone than silva. Any advice? -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"
