If the issue is network traffic, why not create an extremely lightweight proxy 
object for an addressbook entry and have the server return a collection of 
these?

The proxy accessors then can to go back to the server to get more info if the 
client app tries to access a field that is not in the proxy object. 

In huge search result sets, I would imagine that a very small subset would 
need to go back to the server.  With this approach, no changes are necessary 
to client code.

If the proxy can be as light as 100 bytes (name + email), 10,000 entries would 
require 10^6 bytes, which on a modem connection is around 200 seconds (if a 
modem = 5x1024 bytes/second.)  Hmmm, this still seems pretty slow ...

It depends on what people want to search by, I guess. I haven't been following 
this thread closely enough to know the use cases.  If this is mainly for 
things like auto-completion as you type in the email address, then maybe you 
could get away with the first 10 characters of the name and of the email 
address .

Mark
