On a related note (I think?), how hard would it be to build a Groove-like system with ZEO? I have never used Groove, but it sounds like a useful groupware tool for everyman. If the basis of Groove is incremental synchronisation of shared databases, then ZEO seems to offer similar functionality, especially if it encrypted the synchronisation protocol, which is what you, Chris, mentioned doing in a previous post. --- Alastair We at vPatch have also been looking at another P2P system called Magi -- www.endtech.com . It is just coming out with a killer work flow system with explicit work flow -- ie the work flow states are displayed as a work flow graph which I think is necessary when you get more complex work flows. This leads me to the question. Does DC have a strategy for P2P? In our opinion the Application Service Provider model will be superceeded by P2P.
