remote:what if you want your logs to be put on another machine....

null logger does nothing.

I can write my own stuff. but I need to restart zope if I want to change
the zLOG configuration, or hack it in zope and patch every next release.

if I'm fi trying to figure out what's happening with a possible bug on a
production machine, I'd like fi to temporarily reroute all ERROR logs from
BuggyProduct to file dump.txt so that we don't have to wade through the
log output the 300 other users visiting websites on the server, produce, 
since they are  not using the BuggyProduct.

what if I want to split the logs based on some condition....
I have to change code in Zope, and restart the server ...
that's not the way something like this should be done.
