It checks the PageRank of up to 100 websites at once.
It`s easy to install, just copy all the files to your server.
I used http streaming, in this script too, but since it does not work with Ajax, the same thing like in MDCPT happens here. Firefox 3 and other browsers will return the results in a different style (one at a time for Firefox and all at once after all the results are loaded for other browsers).
