In France (i suppose elsewhere also...), you have 2 cases with DSL : ungrouped or not ungrouped.
For ungrouped, provider make generally no filtering on P2P, so no need obfuscation.
The problem is for those who are not ungrouped, the majority !
Majority of providers make P2P filtering with switch layer 3 as Cisco, but not only for applications like aMule but for all P2P traffic, like Skype and other internet game, it's a big problem.
The french historic provider (no publicity...) makes no filtering, ungrouped or not ungrouped, so it can be a solution for those who prefer change their ISP and keep their applications.
So, obfuscation should become a standard for all P2P application if ISP continue to fliter P2P packets.
I have made as others, i have installed eMule 0.47c on WinXP, waiting for an aMule with obfuscation, but for when ?
Thanks in advance for your work.
