767  2.  We see it as a DATA LAYER for a new rational system of computing.  The grotesque inconsistencies and complications of files in their present form-- consider, for example, the issues of readdressing among downloaded HTML files-- may be replaced by a clean, table-like arrangement which keeps track of things more easily-- and which bright non-tekkies can deal with.  2.  We see it as a DATA LAYER for a new rational system of computing.  The grotesque inconsistencies and complications of files in their present form-- consider, for example, the issues of readdressing among downloaded HTML files-- may be replaced by a clean, table-like arrangement which keeps track of things more easily-- and which bright non-tekkies can deal with.

772    -Could we use SDSI/SPKI in our system (it's hierarchical), like in ConChord
773    -is there any other implementations of SDSI/SPKI-like systems ?
774    -SDSI/SPKI is not optimal for us, but somewhat working solution
775    -in our model: trust = trust knowone
776    -give a brief explanation of current techiques in accountability and trus

778    Tuomas' example scenario (in finnish):
779    
780    jos joku sanoo, ett? urn-5 foo on blokeissa X
781    ja j?tt?? blokit Y pois
782    miten systeemi selviytyy ?
783    eli kuinka pahasti pystyy mit?kin spooffaamaan, mill? todenn?k?isyyksill?
784    tai jos vaan ei haluta antaa joillekin koneille jotakin blokkia
785    niin miten helppoa on organisoida sellainen hy?kk?ys
786    tai halutaan hukata verkosta tietyt blokit
787    floodaamalla indeksi
788    mutta sitten poistamalla ne serverit
789    
790    What will happen if, jyu's network connection is broken ? Inside jyu, how do we will self-organise ?
