[Zope] RE : [Zope] Sybase: How generate id keys? (surrogate keys)

The unique id problem come up again and again. The automatically generated unique id will benefit web author with sql row id object id and may be some others With a view that zope will be run over the network with distributed storage across the net, I would like to suggest we implement a unique id server which can be a zope server serving on another port and serialize all request and return the globally unique id. Does this work? I also suggest zope can be configured to automatically get the object id from this service and have globally unique object ids. Rgs, Kent Sin
