as soon as you allow machines to send messages over the network it is going to be possible for messages to be forged. the receiving machine has no way of knowing what is happening inside the sending machine and if the data it is getting is correct or not.

Actually it's exactly the same as with local logging: of correct authentification scheme is used (i.e.: not syslog's UDP) then they can only be forged after takeover. The messages right before takeover are the most valuable. Sure, you must understand that some messages are are probably forged and some are not, but this is always the case when forensic analisys is done.
