this xowiki + s5 looks interesting... I'll look at it soon. Right now, I'm not prepared to deal with xotcl; I would want to know the language and have some experience with it before putting it on a production server. Additionally, wp offers me some things I still want (public/private presentations, permissions to edit/view).
I'm about to thank Emma for pointing me at the solution to the wp add-slide thing; it's fixed now.
