A very nice product, small, concise, precise, and useful. The last is the most important. The feats are neat and I can't imagine a cleric (or any sort of healer) not wanting to take a feat that would allow the extra hit points healed as temporary hit points. That's the good.
The bad is that the product really needed to be proof read by someone who had no idea what the author was trying to say. Example: how long do temporary hit points gained via one of these feats last? And can someone, anyone, explain the text of Lingering Cure? I read it once, went cool Read it again to make sure i understood it, got more confused and then on the third reading gave up.
All that being said I have room for these feats in my campaign. the only concern I have about including them is that they break some of the barriers between the classes. These feats allow cleric to do some things that other classes can do (e.g. the cleric cast CLW on himself as a move like a paladin laying on hands.
And now i that i think of it, it might be worthwhile to explore the possibilities of these feats as metamagic healing feats. That would allow the use of them at higher level and better fit the concept of a metamagic feat.
