I've got a 27" wheel and it won't be true...
... according to the LBS mechanic. I took it in the other day and he said he wasn't able to get it round.
Here's a video:
It seems good laterally, but it has a couple low spots.
Is this anything to be concerned about? My inclination is just to keep riding on it.
This is a rear wheel on a mid 70's Dawes Galaxy. It is a Weinmann rim (aluminum, or at least non magnetic) on a Shimano large flange hub.

The braking might be a little lumpy, but as long as the pads don't go into the tire, there's no reason not to just use it. I've used much worse for various amounts of time.

I'm sure someone much smarter than me can speak more intelligently, but unless you are going to the Salt Flats to break a land speed record, take it for a ride and use your best judgement. You may never reach speeds to notice the imperfections. If you do - re-evaluate

I'm not terribly concerned about speed - I'm more concerned about catastrophic failure. I take it that isn't really an issue?

In my non-expert opinion, it's all about speed. The wheel is sound until the speed is reached which reveals the imperfection. I don't know what speed that is. Your best judgement should be good enough. If you start feeling weirdness - it's too fast for that wheel. I think it's splitting hairs though.

A song popped into my head as soon as I read the title.
I wouldn't worry about that. You won't even feel it.

I've got a worse wheel on the front of one of my bikes right now. It appears the rim is literally bent. I've gotten over 30 MPH coming down a hill with it and never noticed any wobble or wumping. It's annoying to watch though as you ride and it makes me want to tweak on it all the time. But as far as catastrophic failure, what are you expecting to happen?

That's not bad at all, I wouldn't worry. Of course you could walk the town - keep a searchin' all around - lookin' for a street corner wheel.

Unless that rim is being made more round by means of uneven spoke tensions, It looks perfectly serviceable to me and I doubt that I would notice it ever.
In some cases, a mounted tire may either help or exacerbate a rim's out-of-round condition, depending on how the tire is positioned rotationally, so you could try moving the tire around if the out-of-round condition is worse at the tire tread than it is at the rim.
A rim's durability is hugely dependent on the uniformity of spoke tension and on the weight loading, so as the weight loading is increased then a higher standard of spoke tension uniformity should be applied. With some bent rims, a limit is reached here and the correct action would be to replace the rim, especially with single-walled or lighter weight rims and/or with lower spoke counts.
