Iaijutsu Focus as Class skill

[bootzin]

Hey, guys!
I wanted you to help me gather every possible way of getting Iaijutsu Focus as a class skill

What I know are:
Iaijutsu Master PrC
Skill Knowledge feat (although it is supposed to be used with another skill system)
Samurai Class
Factotum Class

What other ways are there?

[ahenobarbi]

Champion of Legacy (iff one of your earlier classes had it)

[Karl Aegis]

Experts can choose Iajutsu Focus as a Class Skill, as can Human Paragons.

[BowStreetRunner]

Exemplar prestige class has all skills as class skills.

The Cosmopolitan feat from Forgotten Realms allows you to make a skill become a class skill for you.

[The Viscount]

Savant (aka prototype Factotum) from Dragon Compendium also has all skills as class skills.

[Troacctid]

As does Ardent Dilettante from Planar Handbook.

[Chronos]

Heir of Siberys has as class skills all skills that were class skills for any other class you had.

[PseudoPanda]

Aereni Focus from Player's guide to Eberron makes any skill a class skill and gives you a +3 bonus to it. Have to be an Elf from a specific region

[Doc_Maynot]

If you're coming through variants anyways (Skill Knowledge), Generic Classes (http://www.d20srd.org/srd/variant/classes/genericClasses.htm) choose what skills are class skills

[Ethelesin]

The Aerenai Focus feat allows you to pick it as a class skill, requires you to be an elf though if i recall.

[Biffoniacus_Furiou]

A single level of Human Paragon (http://www.d20srd.org/srd/variant/races/racialParagonClasses.htm#humanParagon) can make it so that's always a class skill for you: "This skill is treated as a class skill in all respects for all classes that character has levels in, both current and future."

[Ephemeral_Being]

The Cosmopolitan feat from Forgotten Realms allows you to make a skill become a class skill for you.

There are two versions of the Cosmopolitan feat.

The version in the FRCS is exactly what you're saying. Add a class skill, +2 to it for all checks. The thing is, FRCS is a 3.0 book.

But PGtF has a different (much lamer) version which gives a bonus of +2 to a few skills. And PGtF is a 3.5 book.

I thought that anything which got updated mandated the use of the 3.5 version over the 3.0 one. Is that wrong?
