I've also been thinking about the possibility of a Groove-clone using Zope. Seems Jabber (www.jabber.org) might be a way to do this without trying to force Zope to do IM - i.e. Jabber handles the messaging, Zope handles the storage and replication. There's a mention of integration with Jabber in the Zope Book (Chapter 9??), but has anyone played with this any further? And does anyone know why the various python-jabber clients seem to have fallen by the wayside? :-) Cheers, Jon ------------------------------------------ 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
