Doh, you're totally right! NSIS's LZMA compression and the compressed Nmap
source code downloads wouldn't change the size of the resulting file no
matter whether the blacklist was stored compressed or uncompressed. It's
still significantly larger relative to the existing Nmap downloads.

Disk space is cheap, so we should not worry about disk space, right?.
Nmap releases are compressed, so having a compressed file in there does not
make it smaller. I am not sure if compressing the file would help.

Nice work. Why are we worried about the fingerprint file size? Nmap 
all ready ships with operating system detection and software version 
identifying databases. How big do we expect the SSL fingerprint file to
become?

Depends on how much info we want to include with each fingerprint. 
Right now, I've trimmed it down to the minimum of just saying where it 
came from originally, removing all the model/manufacturer/version info.

The other thing that could make the file size balloon is including the 
Debian SSL blacklist. I believe those are in the tens of megabytes.
