Liquid Mushroom Compost

I have just gotten hold of some mushroom compost and am interested in peoples experience and uses for such.
I have used it as a mulch before and plan to use this load to dig into some soil which has gone waxy (ie won't retain moisture, water running off) to improve the soil structure and give it some bulk.
More interesting however, I have also got hold of some liquid mushroom compost. The mushroom farm mixes all their own compost in a shed and adds water to the piles to get the compost piles working. The run off is collected into a sump from where the water is reused time and again to water the compost piles.
I have a 20 litre container of the liquid from the sump. It has the look of a normal compost tea and it was free. If It works well I am going back for more.
Anyone have an opinion on this? Also, I intend to treat it as a standrad liquid compost and water it down 10-1. Any thoughts on that?
