See, I read the swarming feature list, but didn't see PFS in it. Suppose most casual browsers don't really care about that feature
I have some experience using I2Phex (I'm not a coder tho). I agree it shouldn't be spread around at the moment, and this is not an advertisement for it by any means. I just have heard the the guy who did the main work on it seems to be MIA. I thought the devs of mainline Phex could at least capture and preserve his changes. I would not expect you to release them yet or anything, but I'd hate to see his work get lost

I understand his changes could be very vast and difficult to integrate.
Anyway, this is just a suggestion. I understande that the developers will work on what they want to work on, and I encourage them to so they stay happy

Keep on enjoying yourself fellas.
