I can't see the point as well. It seems some people can't use search...
Exactly, and no one has ever denied the possibility or plausibility of such machines, just the practicality of the implementation of same. There's a ton of stuff that's 'possible' but not financially viable. For instance, I could go out and spend all of my cash and savings on lottery tickets and possibly win, and even have a better chance than if I never spent anything. That does not make it a financially viable decision though.
OF COURSE no hash is FPGA or even ASIC resistant. It's just impractical and costly with the current gen technology. There are several DYI and company projects working on SCRYPT FPGA right now, and sooner or later it will be available. The whole POINT of developing a new coins is that you do if on the premise of working and available technology. Hell, when bitcoin came out it was 'GPU Proof' until the first person realized how to do it, and do it well.
Ok and... I can't really see what you added to my previous post regarding that it was of course possible, just not practical at this current point to warrant anyone with serious funds putting a significant financial investment into.
