That is all I can say, wow.
This is the coolest thing I've seen in a long time. A zero footprint cube browser that is built using Adomd.net and ASP.net. I've been looking for this for a long time. But not only is it everything I've wanted, it is free and you can download the source.
My next project will be to convert this into a web part for SharePoint and add save state. Then life will be good and I will drop the Office Web Components (and all the problems we've had with them).
Thanks to Mosha Pasumansky for linking to this and to Duncan Lamb for linking to Mosha. (In case you don't do much with Analysis Services, Mosha is the development lead on the AS engine team and is the MDX/OLAP/AS guru (see his website and books)). I'm now subscribed to Mosha's blog and already learning quite a bit...
