Beginning the planning stage on this, and there is technically a problem with a delay.
Namely that the versions which plugins use is a convention, not a rule.
IE: We're using yyyy.mm.dd as a version (with the possibility of alpha suffixes on it)
Nothing says you have to. It is still perfectly valid to put a version of say 1.0 followed by 1.2, etc (or version of alpha, beta, stable v1.0, stable v1.1, etc) (or for that matter use mm-dd-yyyy)
If the convention holds true, then delays will work. But, if an author decides to go against the grain (and I thought about it once - just to be different) then it'll fail.
Odds on, not going to be a problem, but just something that popped into my head. (And can't check the time of when dynamix found the update, because that date will get reset every time checks for updates are run)
