I like this and I feel it would be a great part of my plan to someday really understand spreadsheets, except I am not wanting to learn anything in MS Office. But definitely seems like a good market to be in, and a nice tool.

I guess you could do stuff like find lots of common VBA, formulas etc. written in the past, from MSDN magazine articles and similar, and package them up as a library of add-ins that you would get as part of your membership automatically.
