The last one I connected to was yesterday whilst using WS. (I'm using Phex presently.)

The only other thing from my manually noted connection log that shows up as 5.1.2 is from 25 June (USA ip) morph500 5.1.2.912 (GnucDNA 1.1.1.4) whilst using Phex. I don't have any record of the LW 5.1.2 connecting to Phex.
But WS & all other Lime based programs will try to connect to a certain number (%) of ultrapeers that are identified as Lime.
