I don't understand this reference. Is there a caster level check to cast an epic spell?

I overlooked this when I read through the fortify seed the first time. I don't think the x10 cost multiplier for epic magic items is a good precedent. (I'm not even sure it is good design!) At 21st level a group of PCs are like a first level party encountering a grick. They don't have any magic weapons, but perhaps one of the spellcasters can magic a weapon for a brief period. A +1 weapon costs 2000 gp, way more than a 1st level party can afford, but the spell is in their reach. Magic weapons won't become expected equipment until probably 4th or 5th level or so. Similarly. the 720,000 gp that a +6 weapon is worth will start to be available at around 23rd level (when it is less than half the PC'ss expected wealth) or 26th level (when it is less than one quarter the PC's wealth: see ELH 23).
Just by parallelism I think that an epic spell that grants a +6 enhancement bonus should be accessible to 21st level characters; it fulfills the same role that magic weapon does to 1st level characters. Which to me means that the spellcraft prerequisite shoudl be less than 24. So if a +5 bonus is available for a spellcraft prerequisite of 16, that additional +1 should be +8 SP or less. I don't see the harm in making it +4 SP. It mimics the jump between magic weapon and greater magic weapon, and would be a fine spell to research first. (Maybe add extra duration to make it last an hour?)
If you make it +40, then.... well, at what level will the characters be casting spells with a Spellcraft Prerequisite of 56? Surely the party will have a surfeit of epic magic items long since.
Also, look at the CL prerequisites for crafting magic weapons. The enhancement bonus can't be greater than 3 times the caster level. This rule is unchanged at epic levels. It isn't multiplied by 10 (requiring a CL of 180 to make a +6 sword!). I think the same should hold for greater magic weapon. Don't multiply by 10.
