I am sure a lot of us have read many many studies
the only hormone that u will get with a fast digesting carb is insulin
it will store th nutrients in you blood stream
which will be done any way at a slower pace if u take in any other starch carb
really - then perhaps you should read some more studies, like the one below, that shows insulin is NOT the only hormone that is effected by a post workout meal:
Dietary supplements affect the anabolic hormones after weight-training exercise

Department of Kinesiology, University of Texas at Austin 78712.
To examine the effect of carbohydrate and/or protein supplements on the hormonal state of the body after weight-training exercise, nine experienced male weight lifters were given water (Control) or an isocaloric carbohydrate (CHO; 1.5 g/kg body wt), protein (PRO; 1.38 g/kg body wt), or carbohydrate-protein (CHO/PRO; 1.06 g carbohydrate/kg body wt and 0.41 g protein/kg) supplement immediately and 2 h after a standardized weight-training workout. Venous blood samples were drawn before and immediately after exercise and during 8 h of recovery. Exercise induced elevations in lactate, glucose, testosterone, and growth hormone. CHO and CHO/PRO stimulated higher insulin concentrations than PRO and Control. CHO/PRO led to an increase in growth hormone 6 h postexercise that was greater than PRO and Control. Supplements had no effect on insulin-like growth factor I but caused a significant decline in testosterone. The decline in testosterone, however, was not associated with a decline in luteinizing hormone, suggesting an increased clearance of testosterone after supplementation.
The results suggest that nutritive supplements after weight-training exercise can produce a hormonal environment during recovery that may be favorable to muscle growth by stimulating insulin and growth hormone elevations. I agree with what you say regarding a solid meal replenishing nutrients overnight - however it is far from optimal. As the study above shows a post workout insulin spike comes from carbs and carbs/pro - but only the carb/pro group stimulated GH.
Also, insulin does not store nutrients in the blood stream - it causes the nutrients to be cleared from the blood and stored in the muscle.
what you say regarding the time it takes for protein to be broken down it somewhat correct - however if you have protein in your blood from an earlier meal or pre workout meal/drink then it would be stored in the muscle along with the glucose from the post workout meal insulin spike. However as the study above shows there is increased benefit taking protein and carbs immediately after the workout. Also i have not even addressed the issue of pro/carb insulin's effect on cortisol, waiting 2 hours for a meal would leave your body catabolic for 2 hours - not a sensible thing to do in the quest for optimum muscle mass, when it can be easily avoided by a shake or cup of milk
I could go on and post more studies, however I fell the above points back my claim enough
