Is Distributed Objects still the preferred method for communicating
among computers on a local network? It's been hinted that DO may be
deprecated in the not-so-distant future. When I asked about DO
recently, I was pushed in the direction of Jens Alfke's Blip.
Thanks.

I use DOs on 10.3, 10.4 and 10.5. They work correctly on all
versions. From your description I'm not entirely sure what you are
trying to do. Could you post a code example and I try to help.
Cheers

I'm seeing "connection went invalid while waiting for a reply" in a
DO
callback. The client passes self in a call to the server; some time
later, the server calls a method on that client (proxy), the program
hangs for a second or so, the "connection went invalid" connection
appears, but the method call is successful anyway, so it would appear
that the DO machinery is re-connecting everything okay.
According to the debugger, the message appears as a result of an
uncaught NSException from -[NSConnection sendInvocation:internal:],
called from -[NSDistantObject forwardInvocation].
Server and client are both properly retained.
There seem to be a lot of messages of late on Apple's forums about
problems with iSync (10.5.4) and even Interface Builder (10.5.3,
IB3.1beta6) in which this message is reported. Is it perhaps a bug in
recent versions of the OS rather than in my code?

P.S. This question has been asked before, but the OP didn't get an
answer (http://www.cocoabuilder.com/archive/message/cocoa/2006/12/29/176458
