Are you sure that you want/need to do all of that rewriting work within 
syslog-ng? There are tons of tools you can run *after the fact* to strip 
out characters or fields in a text/log file.

That being said, you can probably use "syslog-ng-anon",  a 3rd party 
patch to syslog-ng, that will strip out IP addresses (or anything else 
using regular expressions).

The patch has been mentioned, at least once before, on this mailing list.
