I haven't read the entire thread, but has someone mentioned that you can use shackles, ropes, or some other form of arm-binding to simply prevent the use of somatic components in spellcasting, which most spells have? Mix that with some sort of gagging to defeat verbal components, and you've defeated the vast majority of spellcasters.
Yes, Silent and Still spells (and those with Eschewed materials) can get around this, but it at least puts a damper on the highest-level spells they can use. If you're 9th-level, needing to use both of those is going to put that teleport spell out of your normal reach anyway.
For those spells that can still be used by a bound and/or gagged spellcaster, well...no form of restraints that are cheap and easily-applied are going to be foolproof.
