Excelly I saw after my post that it was a 2 year old thread and was already regretting for bumping such an old post. I'll be online tonight (the Netherlands here) in #wowace/#wowuidev/#curseforge with the name Nexiuz. Not sure, I though I saw you there also a few time. We can have a chat maybe there.
I created my own LibAura library (still work in progress) that is providing aura information for my addon. It currently supports aura's on units, spell cooldowns, Totems, Weapon Enchantments and some others that are still not available atm.
The code is not yet optimal and there are a few small bugs that need to be tracked down. But I'm interested in a general aura library that can be used by multiple addons. And I'm willing to share code and help out.
