Display posts from Main blog on child blog

OK smart developers polish up your brains for this one. I am trying to get posts from the main blog to display on the child blog.

Specifically this is for a MarketPress implementation. I would like to be able to specify products to show on a child blog in a certain spot. So I would be creating a page on the child blog that displays products from the Parent blog from an array or something like that.

To start with I just need to know if it is possible to write a theme function to pull in information from a different blog id (in this case blog id 1).

EDIT
Sorry guys this was supposed to be for the community not support. Anyway I found the answer here
