Spell Research effecting feats, traits, etc.?

[DavidWL]

Reading the pathfinder fun finds threat, the following feat was mentioned:
Eldritch Researcher: http://www.d20pfsrd.com/feats/story-feats/eldritch-researcher-story

Does anyone know of other feats, traits, etc. that will modify your ability to do spell research?  Any published sources are fine.

Recent finds:
* http://alcyius.com/dndtools/classes/wizard-of-high-sorcery/index.html --> 25% discount
* Innovative racial trait: http://www.d20pfsrd.com/races/core-races/human

This seems particularly cool as it makes "more legal" the fact that you research spells ... if your DM allows you to take the feat, you then practically have a blessing to research spells ...

Best,
David

Truenaming and Epic Spells
are the closest things I can find.
Which is a very wide bookending of it.

Lots of fluff on researching.
