I have used PFW in the past (a great super lightweight combo when paired with Webroot WSA) but development seems to have slowed drastically in the past year. There have been a few rumors that maybe the end was near so I posed a couple of questions to Greg Salvato regarding development and the future of PFW and this is what he had to say: I am curious as to how any of you interpret that brief but very interesting reply. Reading between the lines, could this mean the end of PFW as a free product? Pursuing various business models/options strikes me as an effort to save PFW by possibly teaming it with another project and/or with another company. Am I reading too much into his comment? What do you think? It would be a shame to lose such a great free firewall when the field of free products has dwindled so much from what it was 5 years ago.
