Asuswrt-Merlin (or XWRT or Cross-WRT) is *CLOSED SOURCE*. It's a port to the R7000 based on the open source from RMerlin, but the author of the port is refusing to provide the sources. I've contacted him and almost got him to release the source, but he later changed his mind and he's refusing to do it. That is clearly a GPL violation and even if I've asked him for the reasons to refuse to release the source code he didn't say.

ST2 distinguishes its own packets with an Internet Protocol version number 5, although it was never known as IPv5.

Many people are complaining about TFA not getting the point of what a IM client should be.

I think the issue is not at IM but the integration with other functions. I know, is something else, but I'd like to have a good IM client like GAIM with support for voice chat, video, SMS, etc. I really hate the GUI of the you_know_which IM, but I'd like to have some of it features in Linux (GAIM or other) also.

There is no client in Linux (AFAIK) that implements at least the TOP 5 features of the TOP 5 IM systems, and I think that's where we lag behind.
