The complication about simultaneous changes must affect all files, surely. The problem with reintegration could be solved by requiring the hoard to contain all the chunks for a hoarded file. In other words, I can certainly see scope for problems, but it would solve a potential shortcoming of the system: namely, that access to large files on a connected client is rather more restricted than it needs to be. -- Owen LeBlanc_at_mcc.ac.ukReceived on 2000-03-01 08:15:48
