Updating driftnet

I am currently using a public computer that does not have a POSIX/UNIX/BSD system installed to disk.
Since driftnet was developed to intercept JPEG and GIF formats, why not rewrite it to pick up other types of files?
Give this a thought. Think about it as an active-progressive form of photorec.
You would use this on open data lines such as educational and medical to ensure the transparency of the sending and receiving public data.From this, a database would be created that can be openly copied while ensuring file integrity. Entries would be openly cross-referenced with positive agreement among all involved.
