Here is a reply from Charles, who as you recall was the person who initially queried me. (from ticket #1682 on Transmission's Trac) Comment(by charles): I mostly agree with livings124 on this. I don't think it's unreasonable for a network-intensive program to require ipv6 hooks in 2009. One possibility, until Haiku actually gets ipv6 support, would be for you to maintain a patch that you could apply when building for Haiku. If there are other, non-ipv6 related issues that could be fixed in the main Transmission codebase, I'd be happy to take a look at those. I replied to him privately : Thank you for providing a reasonable alternative that will hopefully allow Haiku to use Transmission 1.51+ in the intertrim. I'll pass your message regarding ticket #1682 to fellow Haiku developers and will do my best to get the ball rolling for implementing both IPv6 and MiniUPnP, as well as identifying other potential issues. Once again, I appreciate your consideration for OS's that aren't Windows, Mac or use a Unix-or-BSD-like kernel. :) ------ To me, this is an actual path that we can use. I'm hoping that if such a patch is ever implemented, Charles may be willing to include some Haiku specific build option to patch the sources. ....back to the GSoC'09 application.
