[Zope] Re: Zope Solution

[Geir Arne Evjen]

What about speed in this system, is it comparable with CORBA?. We have 
designed our system such that we need callbacks, id. e sending a request to 
the server requires the server to call the client again. Is this possible 
with the xmp-rpc model.

regard,

Geirt Arne
