Oh yes, there's been code floating around for years that uses timing drift -- but it's never anything that, say, gets integrated into kernels or distros or even embedded frameworks. Compared to the number of nodes out there, it's certainly not "lots" of people using haveged. There's just been a lot of fear and nervousness around clock drift approaches, and indeed, entropy gathering has gotten *worse* (via abandonment of interrupts), not better. Hopefully we can finally put all that -- not to bed -- but to the test. Lets find out if clock drift works after all. --Dan
