First, good responses, irdeggman. I'm enjoying this discussion.

This was to equate to the discussion pertaining to traps and skill focus: trapmaking. If a character makes better traps due to taking a feat does that character ahve any intrinisically higher CR? No he doesn't, neither does a wizard with a wand of fireballs - that was the point I was trying to make. I hope it didn't further confuse it any here.
You were responding to me, so I couldn't tell whether you were trying to rebut a point I made or what. For the record, I said nothing about skill focus. I was merely comparing a trap that the BBEG made and spent money on (using his own resources). Spending his money is considered as much a resource as his feat selection.

Which is why traps have their own CR and yield xp when overcome. Magic items while they don't give xp just by overcoming them they are valuable "booty" that PCs can usually use in the future, at the very least they can sell them for substantial money (considereing they didn't have to spend anything to make them). Cohorts don't yield any effective booty, I still hold to equating them to familiars, animal companions and even special mounts in regards to awarding xp- especially if the "improved" versions are taken using appropriate feats.
Trap indeed can be booty. A disarmed, but not destroyed trap could be taken by the rogue and reused or sold elsewhere. Regardless, the correlation is that traps require resources to build (in the form of money and time, though time is a little subjective for a resource in D&D campaigns, and as others have pointed out, possibly in feats and skill points), just like cohorts via the leadership feat require resources to obtain (a feat and time only, no money required though I'd guess most DM's would require money to some degree) and magical items require resources to build/buy.
An animal companion requires no resources at all (unless you consider the 1 day ceremony). It in fact takes nothing at all away from the character, even when (not if

) it perishes. A familiar takes away when it perishes, and unlike the animal companion it requires the same day plus some money. Both are clearly class features though. You get them whether you want them or not. A druid not obtaining an animal companion is not taking advantage of all of his class features. The same thing with a wizard (let's ignore the debate on how useful a familiar is though -- I personally think they suck, especially compared to an animal companion).

One - that is why Leadership is specifically listed as an "optional" feat for the DM to allow or not with a warning that it may unbalance the game. Hence if a Dm allows the feat into a game and doesn't alow the PC to gain cohorts and followers then he is doing the system an injustice - better to not allow the feat at all if it is not going to be used the way it is written (and obviously intended to be).
I agree. But, it is not optional in d20. I don't have the DMG with me right now to confirm whether that is a change in 3.5 or not. Fwiw, if it really is optional, then granting XP or not is also optional because it's essentially a houserule anyway.

As far as the feat being a prerequisite for certain prestige classes - well there are plenty of examples where feats like endurance are prerequisites so this is really not a well placed example, IMO.
That example was only intended to 'prove' that Leadership is a possibility even if you do not gain any cohorts or followers.
