Azrael: As far as I can tell, Psycarnum Infusion is not a once per day thing. It's text reads as follows:
To use this feat, you must expend your psionic
focus. Until the start of your next turn, one of your soulmelds,
incarnum feats, class features, or other incarnum
receptacles is treated as if it had essentia invested in it equal
to its maximum essentia capacity.*
So your empty, or at least less than full, incarnum receptacle is treated as full until the start of your next round. Now, granted, most incarnum feats (including Azure Talent) have fixed essentia investment values (chosen at the start of the day) but I do think that Psycarnum Infusion is a special case exemption to that rule. Therefore, as per the text of Azure Talent:
Once per day, you can invest essentia into
this feat. You gain bonus power points equal to twice the
invested essentia. Once the amount of essentia invested
is chosen, it cannot be altered and remains invested for
24 hours.*
When this becomes full until your next turn, you gain power points equal to twice the essentia invested. Then, Azure Talent empties at the start of your next turn, but the power points gained remain (This is my reading of it, at least. Other readings may be possible). Recover your Psionic Focus and repeat as necessary.
* I believe repeating the text of these feats here to be fair-use.
