 We investigate hyperstructure, flexible user interfaces and custom controllers  
 together as a solution to the information flood from the net. A free software  
 framework to base further research on gradually forms from our production  
 quality subsystems.  
     
 Our goals include:  
   
         1) Interactive hyperstructure: the user is able to connect any two "data items"  
         which will then be "near" each other in hyperspace, easily visible and  
         accessible from one to the other.  
           
         3) Novel interfaces taking advantage of modern graphics capabilities  
         as well as new types of controllers, all built from commodity parts  
           
         2) Teamwork: Ad hoc and non-centralized Peer-to-Peer version control of  
         structured data. Two or more persons can form a small team to change an object  
         and subsequently submit those changes for consideration by a larger  
         group. The software will manage all versioning.

182    We study of building a location transparent, hyperstructured desktop
183    environment. As a part of the this project, we perform research on novel interfaces
184    taking advantage of modern graphics capabilities as well as new types of
185    controllers, all built from commodity parts. For location transparency,
186    we study the suitability of methods used in Peer-to-Peer networks
187    to find efficient methods for locating xanalogical media from the Peer-to-Peer
188    network.
