Can Excel Spreadsheet Cells contain Objects directly?

PyXLL (www.pyxll.com) allows for OO programming in Excel with Python. Object references can be returned to the sheet and it will keep track of references. There are examples included that show exactly this. I also know of many other addins developed in various companies internally that use exactly the same techniques so I don’t think this is a new idea.
