An easy way to do what Gary suggests is to use Front Page 2003's Data View
function.
You select this when you have in FP opened the site where you want the
read-only copy to appear; then you access (right-hand-colum) the list in the
other site you want to get the information from; you then place the
resulting web part on your page.
It's very straightforward and probably easier to do than to describe
But it is very much a read-only copy of the other site's list. Amendments
can only be made in the master copy in that other site. Also you will need
to refresh your browser to see the latest information; the copy is not
updated on a change in the master without such a refresh.
Hope this helps.
