Martin's Twitter Feed reports that a few Irisbuses now feature advertising, and I spotted one myself this afternoon. They are right hand side adverts that sit under the window line, and I'm pretty sure it ran from wheel to wheel, with the ACTION logo moved a bit closer to the front of the bus.
The ads are for:

343 has this as well
Clarification on the positioning: It runs from just next to the fuel cap up to the front wheel. The ACTION logo has not been moved, so only the circle logo is visible.
333 also has the side ad. A few Irises have a different, smaller ad on the back for ACTSmart.
330 also has a rear ad for ACTSmart along the lines of "Get $500 Moneryback....."
Spotted the side ad on one of the Scania's this evening, they quite suite the sides of these buses (colours & all)
This is how the ad looks on Bus 314:

Pity the ad is crap, but I like the positioning on the Irises, with just the ACTION logo showing.
