Web presentation of Open Office slides

Motivation

TODO: Describe why viewing talks directly in the browser is desirable

R1: Viewing talks with slides directly on the web
R2: Not requiring visitors to have Open Office installed
R3: Not requiring people to download the presentation
R4: barrier-free, (e. g. text view of slide-images, display transcript of audio)
R5: Support for all common browsers, including older browsers that are still in common use
R6: Support audio
R7: Audio is optional
R8: Support for small display screens (e. g. tablets, mobile phones)
R9: Should work without flash plugin and without JavaScript but may use these technologies if available

ok R1
ok R2
ok R3
fail R4: Requires Frame-Support in Browser. There is a html view that would work without frames, but it's not reachable from the start page.
unknown R5
fail R6: For audio an embed-tag is created which only works if the files are saved to disk but not in the world wide web
ok R7
fail R8: bulky frameset, slide images is not resized but gets scroll bars
fail R9: requires JavaScript for navigation

Use OpenOffice HTML-Export as base
- with frames
- with notes (if there are notes)
- browser colors
- black arrow icons without borders
