Elektra,
I was about to grab a copy of meshlinux for my community's project when I ran straight into 404. I also checked web.archive.org, but no copies were stored. If you happen to have a copy, let me know: I really could use it.
I'm sorry, the project hasn't been updated in a long time. It is unlikely that I will take up development on it again. I'd recommend to use OpenWrt for X86.
maybe you could update the wiki with that information ? It could help save some time for the next person. :)
Cheers, Marek
