How does this sound? At the end of this message is the output of

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.

I committed lzma compression for the nmap installer. Here are the
results of testing it on the winpcap-nmap installer.

zlib         720288
lzma /SOLID  433535  60.19% of zlib

And here is the effect on the overall nmap installer.

zlib-compressed winpcap-nmap  14225186
lzma-compressed winpcap-nmap  13947278  98.05% of version with zlib-
                                       compressed winpcap-nmap, 82.91%
                                       of original zlib everything.
