Amoeba Wiki
Amoeba wiki is a text document sharing system for mobile wireless devices. It gives users ability to write text documents and share those documents over wireless network in dynamic manner. Sharing happens when two or more devices are on same radio range. Users can then collaborate with shared documents.
Document in text format is using web technologies. Document is presented in browser and source of the document is served by simple http server. Server tracks documents from the file system directory. Server also interacts with wireless share manager, that discovers other devices and communicates with them. Wireless communication is using bluetooth.
Audience for amoeba wiki is group of mobile users who might want to spontaneously collaborate on text information writing.
