It should be fine. Hundreds of sites is not really that many. You just
need to have backoffs etc. to avoid getting blacklisted. Using sync
and friends would make implementing this easy.

If you want to extract unstructured data, there is some good reading here:


Probably roping together various existing systems would be the
efficient way to get a scalable solution working. See Apache Tika and
projects referenced above. There is also a surprising amount of work
on "scalable web spider"s. (Google that phrase if you're interested.)
