It sounds wonderful!  Thanks for testing.  As you know from our
investigation today, the Nmap Windows executables are the biggest
bandwidth hogs on the site.  I like the idea of enabling this on the
Pcap installer too if it helps.

LZMA is probably most famous for its use in the 7-Zip 7z format.
Maybe sometime we'll distribute Nmap in 7z format too.  I just
installed p7zip (http://sourceforge.net/projects/p7zip/) and here are
the sizes for the Nmap 5.30BETA1 package:

41082880 nmap-5.30BETA1.tar
12965256 nmap-5.30BETA1.tgz
11273966 nmap-5.30BETA1.tar.bz2
10005965 nmap-5.30BETA1.tar.7z

That is greater than an 11% reduction in the bz2 size for the 7z.  It
almost even beat the 10MB mark!  Too bad my "tar" can't deal with
it.

Cheers,
-F
