How so? Why would you only want to AtomPub-publish stuff that are read
from files? Rather than read from other websites (think cross-site
XHR), or stored in offline storage, or received through postMessage
from another site? An AtomPub widget that you instantiate in an
<iframe> and to to via postMessage sounds very plausible.
