Wishlist:Add total unique TB shared on the hub

[marcefanitoli]

Currently there is: # of users, # of TB shared, and average GB shared per user. Unique TB shared would be an easy and useful addition.

Useful? Perhaps. Easy? Absolutely not. Computing the unique amount would require downloading the filelist of every user and removing all the duplicates, which is linear in the total number of files shared. Computationally, it's doable, but all that extra traffic from everyone downloading filelists would bring the real filesharing to a standstill.

Even if only the hashes were transferred instead of the full filelist, you're still looking at 24 bytes per file, meaning for a hub of 500 users and each user sharing 1,000 files (both small estimates), this would take 11 MiB to compute.
