TextEdit on Windows side?
I tried a few wikis that were in virtual machines too as those would be the most portable ones.
And this one seems to be most what I looked for -
http://www.vmware.com/appliances/directory/910 so a Jumpbox VM for DokuWiki. As it is stored in a virtual machine, I can bring the virtual machine if I need it with me on another computer even on a memory stick.
And I've never had database issues with Dokuwiki while using it for a few years at work for team pages.
Plus .. well, I can copy pages easily from an existing dokuwiki to it.
Yay.
