Not a perfrect solution
I tried to open some LibreOffice presentation with NeoOfice and experience was very painful. Editing with bullet ponints and sub-bullet points was hard. The format of the document refused to play to my liking, and was painfully hard to change. There is a free version of the LibreOffice that you can download for Mac. If you are going to use NeoOffice to view LibreOffice documents, I would advise against spending money.
