That should now be easier to do in the current snapshot, if you read
Haobo's comments describing the new commands he's added in:

http://www.isi.edu/cgi-bin/nsnam/cvsweb/ns-2/tcl/lib/ns-packet.tcl?rev=1.40

It will be interesting to see what revising the entire test suite to
only use the headers each test needs does for validation memory
footprint/time, with:

remove-all-packet-headers
add-packet-header <just what each test needs>

_not_ a good idea for example code, mind.

hey, ns might validate on punier machines.
