Nessus 1.1.14 also implements some IDS evasion techniques described in
Newsham's and Ptacek's paper. The neat thing is that it applies them to
every Nessus check (on any TCP port). So you can test an IDS by doing a
scan with IDS evasion off, then re-do the scan with IDS evasion on, and
compare the results (which is quite interesting, because Nessus usually
generates a _lot_ of signatures).

For more details, see http://www.nessus.org/doc/nids.html
