...Yet  it  comes to show the deficiency of caching. Check too  frequently
and hog resources; check infrequently and present out-of-date information.

Frankly,  I quite liked your idea of using <iframe> or <object> to isolate
feeds.  The entry to the dashboard can otherwise become slow and very much
a  'necessary evil' to those of us who don't work around it. To say  more,
in  reference  to  another route down this thread,  the  proposed  AJAX/JS
solution  would  hinder  accessibility, so this seems  like  a  relatively
poorer  solution. A customisable dashboard (/a la/ Widgets) seems like  an
optimal solution to me (just my humble opinion).

As  to other ideas: data prefetching for feeds, use of stylehseet to alter
the  order/flow  of content and thus the order in which file requests  are
made  in  most  Web browsers. There are several such  subtle  optimisation

Best wishes,
