Michael,
I don’t think that Automagic will work with OpenOffice as it uses alot of Vbscript macros to perform alot of the clever stuff inside it. I don’t think that OpenOffice has a Vbscript compiler in it so I doubt it will work with that.
I haven’t personally tried JOverseer on a Linux box, but it works fine on Mac and Windows, so I’m confident that it will work great on Linux. I can confirm that Automagic will not work with OpenOffice because of the scripts/macros. In fact, Automagic also does not work with MSOffice for Mac 2008 for the same reason.
ME Assist is Windows. JOverseer is Java (the J…). I’d assume Palantir is Window’s also, but that should be a non issue as MEA or JO give better maps and information, JO allows you to create and upload orders. All other software should be discontinued, IMO…
