well, you can write it down :), craft a blank skill book, craft the relevant scroll, create the relevant book :), there you have it, there is an ingame way to write down your knowledge!
Unless you don't have crafting, then there goes, your character may know how to launch a fireball but it's not smart enough to write it down for other to learn it :P
A temporary loss of 10 skills to relearn 9 of them 90 seconds later is not a permanent loss of 10 skill, it's a permanent loss of one skill, the collateral is one skill and some gold, not 10 skills.
I think there is a mod already that make skill books on respec tho? I'm not sure, never had to respec.
