The problem of gnutella (greed) could maybe reduced to one word:

lobbying

The guys from GDF found each other about a year ago, worked together, improved something and are proud of what they did. Now they defend each other also if one or two member are a bit selfish. They tolerate as long as they still can participate somehow. If someone found a improvement, they are telling each other compliments and make it a standard, it works somehow. very human. frustrating for every new developer or every developer that is fallen from the noble table of the GDF. The GDF gained the status of a high society, ignoring what's going on outside. With that perspective in mind I can perfectly understand Limewire, they really believe they are doing a good work, there is no harming greed and Bearshare is a cool business alliance.

Unfourtunately Gnutella is not GDF only and GDF decisions outside the GDF do not look that bright, so do Bearshare and Limewire look not that bright. How many users and devleopers do need to complain until the GDF is becoming more open and a true gnutella developer community. No, Limewire is not the big evil... nobody told this... but some non-GDF developers do not tolerate their politics (as they don't tolerate bearshare).

It must be a suprise for you, but things have to change - or - Gnutella development will be splitted more and more. Don't close your eyes and talk about unimportant megapeer details, the network is splitting now.
