This is a fork of openoffice.org right? what are it's differences?
No, it's server-based (apache, PHP, MySQL) software for collaborative working http://wiki.opengoo....rg/doku.php/concepts
AFAICS, the only documents you can actually create on-line within OpenGoo at present are WP and presentations that are saved as HTML, but you can upload/download any type of file for work offline, tag them, comment on them, check them in and out, manage who can see and work on them, and link them with other objects. So yes, in that sense it will interact with OpenOffice, but it's a very different animal.
