[Server-devel] XSCE Sprint

[Tony Anderson]

Hi,

I think this should be done in the overall context of XSCE as proposed 
by David Farning. I think of what I am doing as a system and not as 
isolated pieces. The ds-backup is independent because it only addresses 
backup and restore of the Journal. However, this is going to become more 
a system element as deployments turn to the shared model. It may become 
moot, if the community abandons dependence on Sugar.
