Idea: mabey pointing -f to a executable uses it to verify adresses

[walksanatora]

so what if would be lets say ./mkp224o -f filterProg would run basically filterProg "$DOMAIN" we could do more interesting things like checking the URL for anything in a filter at any point in the url, not just the start

[walksanatora]

another idea would be to spawn filterProg as a sub-process and just feed it information throught a ENV var (like what thread it is) and pass Urls through STDIN

[cathugger]

anything else than shared memory based feeding would be too slow to be worth it imo, and at that point you'd need to use this thru specialized interface, and would end up losing some speed in the hot loop anyway due to cache area loss.
i think just modifying mkp224o would be simpler instead of doing that.
