I read this small snippet and though it might be interesting to folks, I was suprised myself that some of the well known programs use this open source item.

GnucDNA has become the core of many P2P file-sharing networks and programs. While many lesser known programs use GnucDNA, high profile applications such as Morpheus and iMesh also utilize GnucDNA. GnucDNA provides developers with the primary components to the Gnutella network, or to create their own network.

Basically the change is to make sure that anyone making cash out of releasing a client with this component in, needs to obtain a commercial licence ,
which is after all, only fair , but for ordinary folks we can help ourselves as normal..lol

you didn't know they used it?

if you use a client like shareaza that lists the client details for people then you see very few that aren't either shareaza, limewire or GnucDNA
