In reply to the earlier question about how the firewalled host downloading works, this change really benefits everyone on the network. It does not improve downloads for people who are already firewalled. If you're behind a firewall, you already cannot download from other hosts behind a firewall simply because there's no way to make a direct connection between the two.

Rather, this change improves downloads for people who are not behind firewalls, as it makes it more likely that they'll be able to successfully download from firewalled sources. This is because the firewalled host returns "proxies" in the query hit that tell the downloader multiple paths it can take to download the file (to have the downloaded source open the TCP connection after a push request, and then transfer the file).

Hope that makes some sense.

Limited automated requerying
 

Maybe you could reintroduce automated requerying, but limit it to one single requery every 15min or so.

For 4 files it would take an hour to requery them all, but I think that this is better, than flooding the network, and still makes it possible to leave LW on for a night/week/month and to know, that the files will eventually arrive, even though one is away.

That would also increase the number of sharers, and increase the uptime of hosts.

I hate micromanaging my progs.
