SiteMesh style mashups with Rails

Has anyone done any Sitemesh stye mashups using Rails? I want to grab
an entire HTML page from another site and mash it into my sites layout/
chrome. To do that I would need to strip the head section and the
body tags and just plop in the guts. I might also need to grab any
links to javascripts or images out of the remote page’s head section
and put it in my head section. Has anyone done something like this
with Rails?

Thanks!

Steve
