Within RHEL4, they are very much the same. But some improvements with each 
release. Between RHEL4 & 5, the user interfaces at the program level are the 
same. The audit utilities understand the same parameters, audit.rules has the 
same syntax, etc. The API at the library level has changed somewhat due to 
new capabilities in RHEL5 and the kernel.

Between RHEL4 & 5 they are mostly the same. I'd have to know exactly what you 
are trying to do to answer it, but we've worked hard to preserve the same 
command set. IOW, "audit -w /etc/shadow -p wa" runs on each platform. The 
audit records are slightly different format, but contain nearly the same 
information.

This is the area that we are working in right now. RHEL4U5 has a realtime 
interface which can be used for log aggregation. We are starting to turn 
attention to that and should start fleshing something out in the coming 
weeks.
