There are two major parts to your metasearch problem:

  1. Communicating with multiple servers concurrently and fielding their responses as they reply.

    This part is relatively simple using threads.

  2. Keeping the user aprised of the progress by updating their browser window in real-time without using refreshes.

    Sorry, but I am not a web guy. I know almost nothing about AJAX beyond the name.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
