If I'm working at the airport or away from a network connection, I would
still like to see the logs. Also, logs are probably not going to change
that much after a commit that the old information would be worthless. I
can always get the new logs when I'm reconnected.

Finally, regarding disk space, if we are already storing a copy of a
revision in the .svn directories, then storing a log doesn't seem like
a lot of extra space, maybe 1K at most in the text.

As cvs does this currently and I would like svn to replace our cvs
repositories, is this something we can add?

Well, I'd rather have svn make my work easy than having to remember to
do that. If I forget to run svn log, then I'm screwed?

My bad. I ran a cvs log but didn't let it run to completion. It does
make a single connection to the cvs server.
