Only useful way I can see in using them (for the IPB's I visit) is for news areas where you can put the company logo next to the topic name. I wouldn't make it larger than a normal emote though otherwise it's way too distracting.
April Fools!
Anyways, while I do have to wait for IPB3 to launch my site I don't mind waiting as I know the product will be of higher quality and up to par with the rest of the IPS products.
