one zope ODB into another. Using XML-RPC or something to connect the two sites togeather over the internet. It may not be fast enough for using that way but at least it would be really easy for transfering data between zope odb's.
We are entertaining the possibility of putting ZPublisher.Client into the _ DTML Namespace. I am primarily championing the idea.
'Client' offers many cool uses. 'Client.Function' will call a remote 'Zope Method' which marshals simple types around (int, list, tuple etc.) and act as Zope oriented RPC. 'Client.call' is a convienent wrapper around 'Client.Function'. These both have the upshot of working with any URL, turning non 'object content' into file Message objects and return them in a list.
Even cooler, 'Client.Object' will create surrogate objects of remote Zope objects. If you have a DTML Document on machine A, then Machine B could say:
<dtml-with "_.Client.Object('http://A/YourDocument')"> <dtml-var id> </dtml-with>
and print 'YourDocument'. You can pass autentication information in to all of the calls to access restricted object.
So what would happen if this wrapper object was passed back using a <dtml-return> call or even a __bobo_traverse_ method? Would further resolution in the object happen using the link or would it break and start trying to find objects in the local context?
