[plug] presentation software

[Marcos Raúl Carot Collins]

Hi there!

Do you know of any software, preferably Linux based, that I can use to
display information, both live and pre-recorded (for example an
openoffice impress file, along a rss feed, and some html, in different
parts of a screen) for displaying in the information big screens of a
Library?

Ideally it will be server-client (design the view in a client, upload
to the server to be displayed)

Thank you!
