I did something along those lines a few years ago but the scripts for it are long since gone. The basic workflow was to compose the deck in LibreOffice and then do a few conversions: - ODT -> PDF - PDF -> directory of PNG images Then all you need is a basic web page with an image and some nav buttons, coupled with some JS that knows the list of files and can update the image's URL based on nav button clicks. At the end you have a portable web slide deck. Fancier setups are definitely possible (you could for example mimic multi-monitor presenter mode by having multiple pages where one drives the other via websockets, or even just add a timer and presenter's notes) but it gets around having to hope that the other side has a decent PDF reader or a presentation editor that likes your preferred file format.
