This snipped get the latest rss links from delicious from a DELICIOUS_USER that you have to define in your settings.
I use this snippet in the trespams code blog to inform the visitor about the last links I have bookmarked.
This is a modified version of snipped 819 to allow using any variable in the template to obtain the results.
It also added a 6 hours caché for the rss.
