Cabos is an interface to LW for multiple platforms.
GnuApp is iMesh
morph is Morpheus
mxie is ??? never heard of it, it seems to use an old version of GnucDNA. Never uploaded to them, I'll add them to my ban list.
The weird caracters from the browse host is a known bug of agent decoding I reported since LW 3.6. It happens for other clinets than Raza, like Bearshare, LW and all.
Ciao
Edit: mxie is a browser with GnucDNA
http://en.mxie.com/ It sucks.
