I am a user of Windows XP and i think the extension evoice is an important
feature to impress because this extension offer easy and powerful sound
presentation, like it is showing in this article
http://www.linux.com/articles/127502.
But I see it is impossible to send a presentation with a sound evoice to a
friend or an other pc because the sound is not associated with the file. The
default link of the extension save in local user settings and it is impossible
to send it whithout making same link (with name of user in a shadowed link...).
Unfortunatly it was difficult to contact the university who has created the
extension and it doesn't seem easily to modify evoice.oxt and the bug stay.
Maybe to help teachers, but for all people who want a great application with
sound player and recorder, u may integrate evoice like a component of impress.
