aggregate content in network (theme)

this is a “neat” theme… will it aggregate content from other sites in my multisite? it does not appear to be doing this by default – but seems like a perfect feature for it.

our implementation is for an “intranet” (all pwd protected) – we have a main site that i aggregate content from all of our staff members on. each staff member has their own blog – so they can mess around, have custom theme, etc.

id like network to show the posts from all of these subsites.

is this possible?
