You can cap the daily spend for an ad and adwords will keep things below that.

Yes, although there's a trap here (or used to be, don't know if it's fixed): the spend starts at midnight and goes through to whenever it runs out, so you end up only advertising in the mornings.

AdWords has an option now to distribute your daily budget evenly throughout the day.

Yeah I do see the daily cap, but still no lifetime. Curious how people manage lifetime caps.
