...solubility of alpha acids in water at varying temperatures to work out what % of alpha acids you are removing by steeping them first. While you are at it you could see what the difference in solubility is when the 'steeping' solution used contains sugars/proteins etc.

Will do. At the moment my experience tells me "some", but not much at all of the AAs leach into the fermenting beer from contained dry hopping. A small enough amount as to be less than my tastebuds can discern.
But I'd like to know the numbers too as you've said with what's in the solution and how this changes things.
A very simple experiment could easily be done by letting say, 20g of hops steep in 5L of water for 4 days and then boil it for maybe 20 minutes. If there's perceivable bitterness then the AAs are coming out. If not, they ain't. Perhaps steeping them in fermenting beer (with an alcohol content) might leach more AAs...
