Disguise spell casting methods

[Shfish]

Other than eliminating the V/M components and then using secret signs to disguise the remaining part, what other methods are their to disguise the casting of your spell? Or at least make it harder to figure out?

I know there is the Illusion of calm, but that doesn't disguise the verbal component, so as per RAW enemies can still ID the spell.

Any other routes I'm not aware of?

• Being out of sight and in a noisy environment.
• the Spellsong feat.
• The Rakshasa bloodline.
• Dawnflower Dissident PrC.
• Pre-casting touch spells.

Unfortunately that actually doesn't do it as per rules as written. I am looking for options that are more strongly supported by RAW. I agree it should but...

By RAW if they can see you they can spellcraft the spell. I think there is a way to make the DC +5 higher from a class ability, but that is about it.

PS: I just notice VRMH's list. The 3 in the middle might work. I dont have them memorized though.
