is there a way to output in a node instead of a block?

There is no easy way to do this.

If you have a look at the delicious module method delicious_block_page() there is the following query that will help you in the right direction ..

$query = "SELECT DISTINCT dl.description, dl.href, du.user FROM {delicious_link} dl LEFT JOIN {delicious_tag} dt ON dl.lid = dt.lid LEFT JOIN ...

With the above query as guidance you should be able to create a node with PHP content which displays your delicious links.

Hope that helps.
