I've primed with honey with solid results. I've also placed honey in the boil (my first batch, didn't know any better) but you'll get better results if you do it during either the cool-down (under 100-110F) or after active fermentation has slowed a little (after the first week at least). Be careful with how much you add to a batch. Using more honey will start to swing your beer more into a braggot. Although, you need to add a significant amount of honey to get to that level (typically 50% of the grist being honey is when you approach it being a braggot).
If you want more honey LIKE flavor, use honey malt. If you want to add a specific type of honey flavor to a brew (honey malt is more generic) then use that type of honey in the actual brew. You don't need to add all the honey during just one stage. So, you COULD put some in the boil (I hear a million bees screaming out all at once), some during cool-down, and some post active fermentation. You can also prime with more.
If you're going to prime with honey, use 1.25x the amount of sugar you would have used to get the same CO2 volumes level for the brew. Do NOT add honey by volume, use WEIGHT measurements ONLY. The only thing going into my brew that's measured by volume is water. Everything else is by weight. So if you were going to add 4oz of corn sugar to prime a 5 gallon batch, use 5oz of honey instead.
I've changed from using honey to dememera/turbinado sugar for the last two batches I've bottled. I'm waiting for these to be carbonated before forming an opinion of the differences. I'll probably have another batch bottled, before I open up the first one primed this way.
For those saying you won't notice the flavor addition from honey, it all depends on the brew, and your pallet... I'm sure a good share of people won't notice any difference. But some will notice a little something different... They might not be able to place it until you tell them how you primed the batch.
I suggest experimenting with using different priming sugars until you find one you really like, and get solid results with. After all, just because something is accepted by the masses, doesn't mean it's the only way to do things. I would just make sure you use a sugar that CAN be fermented...
