progress tracker on uploads
 

How about being shown the download progress
of someone uploading not just their speed.
Like Limeware.
Could be just from you, or could be more detailed by breaking
in to multisegment indicators showing how close they are to
get the whole file by other sources as well.

Maybe show how many times before they have connected to you?
ie known host, friendly?, uploads, downloads, shared file numbers.
Sometimes stats are interesting.

Another thing is if you find a file that was hard to find, then
it would be nice to browse the host. More than likely they
are also downloading the same stuff as you. Searching is
sped up. If you select everything on this host I am assuming
Xolox will search out other sources of these files still.
