[Zope] Do these work properly in 2.3...

I'm having a terrible time getting the Virtual Host Monster to behave itself with Zope 2.2.5 and SiteAccess-2.0.0b4, so I'm thinking it's time to bite the bullet and upgrade to Zope 2.3. But various sites I host depend on various products, and it's typically not evident whether they all work as expected in 2.3, specifically: DataSkinAddons JPicture Renderable Squishdot ZDebug ZPatterns EventFolder LoginManager PythonMethod (Ok, so you use PythonScripts. Do they magicly upgrade?) TransparentFolders ZNavigator ZWiki Any upgrade experiences with these products would be enourmously useful TIA, John
