Both the bard's "Bardic Knowledge" feature and the druid's (and ranger's) "Wild Empathy" feature are fundamentally equivalent to skills -- they're based on attributes (Int and Cha, respectively); improve by a single point each level (basically a dedicated skill point); and they're treated in the adventure scenario in much the same way as skills such as Knowledge or Diplomacy.
If you wanted to allow a character access to those exclusive skill-like features without requiring he take a level in the bard or druid classes, how would you work out an equivalent trade? What would he have to give up to gain the feature?
Also, a tangential question:
If we allow access to Wild Empathy (as a skill) via a special feat, which option would you prefer? 1. The character can use his Diplomacy skill on animals as well as people. 2. The character must develop a separate skill called "Wild Empathy" by assigning skill points (separate from Diplomacy).
