I've often thought about changing the default OpenSim.exe logging configuration in a similar manner 
so if there are no major objections I may try and do this fairly soon.

By the way, there is a wiki page for logging in OpenSim at

http://opensimulator.org/wiki/Logging

which already contains logging information.  There is /some/ useful information on the wiki :)
