I think what he wants is a Magic item generator that uses all the WotC Books.
You know, one that can roll up the treasure to include scrolls with spells from the complete books, and magic items only detailed in "races of the dragon" and whatnot.
Personally, I'd like one of those! I mean, (grabs a random book off his shelf) Complete adventurer has 7 new weapons, 13 alchemical items, 8 alchemical capsules, 7 alchemical weapon capsules, 9 new toolkits, 9 masterwork instruments, 2 new magic armor types, 2 new magic weapon types, 7 new specific magic weapons, 2 specialist rings, 8 potions / oils, 84 new spells for scrolls, 13 new wands, 21 new minor wondrous items, 5 new medium wondrous items, 4 major wondrous items...
And none of them will ever show up in your typical DMG random treasure roll unless the DM modifies their own table.
