VexTV is one of the less known OpenNap clients. They have just released a version (0.50) with multisourcing capabilities, claiming it works also over different OpenNap networks. The client itself is very small (only 140 k) and uses web-style interface which is probably (haven't yet tried it myself) much less sophisticated than WinMX or audioGnome but some commentors seem to like it. Anyway, this is an interesting technological step and I wish that e.g. WinMX would also consider supporting multisourcing on OpenNap.
