In a Master Page I need to insert a Data View that pulls information from the parent site. I believe I can do this with a Content Query Web Part but I cannot put a web part like this into a Master Page.
EDIT: What I want to do is make the contact info for my company editable in the browser. The contact info is in the footer of every master page that will be used on any site and subsite. My current way of doing this is make a list with an entry that has the contact info (phone, address, etc.) and then insert a Data View web part into the footer of the master page. This works fine if I make this contact info on every site but its against my religion to make people change the same thing in 5 places (if they have to change the contact info in the future). What I want to do instead is have 1 list with 1 entry that have the contact info and point to this entry from any site I need to. That way my company can then change the info in a web form in browser without code.
