take a look andy's zsyncer product ... http://www.zope.org/Members/andym

Does ZSyncer preserve modification dates? I mean, if one copies a site using this product will invididual objects in the newly minted copies have the same modification dates as the originals?

No, I believe it changes the modification dates. This is how it knows what is out of synch, unless I am very much mistaken. I'm less sure of the behavior of import/export, though I think it changes dates too. IMHO, if you are moving a site en-masse, I think you'd be better off to use import/export. Zsyncers value would seem to be in moving small changes from the staging site to the production site, after having made the initial deployment. I am still not happy with the mechanisms for staging a site when it is necessary to merge-back changes originating from the production site (e.g. user comments which have been added to a website). This requires some very careful thought on your part, if you have such a requirement (I still haven't figured it all out, so I would muddle the issue with any specific recommendations!). Of course, ultimately this is what ZEO is about, but it's an automatic method, so I don't think there's much opportunity to intervene in the process and copy selectively. That's what Zsyncer does. There is a hack to Zsyncer to make it reversible (I have a copy emailed from the original author -- it may not be available on the web, yet), but it's supposed to have some significant bugs with the file time handling. It does the synching manually though, so it's not like a CVS check-in, where you get the *most-recent* version from either site. That's probably what I really want, but I don't know how to set it up yet. I've been meaning to look into that, but haven't found the time. sigh. But it does exist. Ultimately ZEO + versions may be the "right" way to do this, but I haven't even begun to figure that out.
