will disabling mojito DHT capabilities and TLS help? will it stop other users from making connections to my computer or vice versa?

I guess i cant use torrents at all in limewire since, i'll be uploading at the same time i'm downloading and I dont want my uni to find out that i am uploading. am i right when i say that?

when i am downloading a file from 10 hosts (for example), then it means that i am making 10 connections to 10 different pc's and i will get faster downloads, thus taking up bandwidth and slowing down the network?

what is better? downloading from 10 hosts at 100kbps or from 1 host at 100kbps? is there anyway of limiting the number of hosts u download from, for example, limiting it to not more than 5?

i am noob regarding this and thats why i'm asking all these questions. sorry about that, but it will really help me if i can get the answers.

thanks.
