But the Wizard cannot scribe the Cleric's scrolls. He can only scribe scrolls of spells he can cast. That is clear from the feat description. Unlike, say, Wondrous Objects, it is not possible to have a different caster provide the spell prerequisite. The same is true of potions and wands.
The rules for item creation seem to indicate that you can always share prerequisites. The wording of the feats always is about "you" meeting the prerequisite or knowing the spell, but the rules for item creation say this:
http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm said:Note that all items have prerequisites in their descriptions. These prerequisites must be met for the item to be created. Most of the time, they take the form of spells that must be known by the item’s creator (although access through another magic item or spellcaster is allowed).
I suppose it could be interpreted differently, but the feat statement would seem to be modified by the caveat in the item creation rules, above. This is supported by the identical language from the various creation feats. For scrolls, potions, wands, and staffs, that verbiage is as follows:
http://www.d20srd.org/srd/magicItems/creatingMagicItems.htm said:The creator must have prepared the spell to be placed in the potion (or must know the spell, in the case of a sorcerer or bard) and ...
The only difference between that and the other items (rods, wondrous items, weapons, armor) is the addition of the phrase, "If spells are involved in the prerequisites for making the [item]." (Oddly, rings have different verbiage.) This distinction is likely because there are some items from that set that do not have spells as a prerequisite, whereas potions, scrolls, and the like all have spells as prerequisites. Those prerequisites still seem to fall under the umbrella of the parenthetical "... access through another magic item or spellcaster is allowed."
Though the quoted text is from the online SRD, I found similar language in my perusal of my (3.5) DMG.
