I have created an updated version (V0.2) of the proof-of-concept. The major change is that sisbit now knows how to display JPEGs and I have created a very simple slideshow script that can be used from Xterm to display slides.

Instructions on how to download and use the software are now on the project web pages: http://xsisusb.garage.maemo.org/. Please disregard the instructions given earlier in this thread. The "how-to" on showing PowerPoint slides is at http://xsisusb.garage.maemo.org/powerpoint.html.

There are still several additional tasks which we really need to complete including: optimising X-server updates; creating a more powerful slideshow script; and further researching the Powerpoint display options to be able to have good quality and high speed both at the same time! If you are interested in working on these or other developments, please look at the project pages on https://garage.maemo.org/projects/xsisusb/ and join the discussion list. You do not need to be a developer to help with these!
