Thanks for the info.

Ultrapeer bandwidth: I was referring to upload of shared files, not messages. Sorry for the confusion. I have about 1/5 of the uploads of what I get when I run as a leaf. My thinking is a high percentage of ultrapeers (read: hosts with reduced file upload capacity) is bad for the network.

Redundant connections: TTL solution makes sense, although it still seems that the higher the number of Ultrapeers, the higher the chance of circles, but I guess there are reasons for more ultrapeers.

GnucDNA: This sucks, there seem to be many, esp. when counting Morpheus. :-(
