I'm working on a platform which uses KVM and can run builds on pretty much any platform you want. It's still in alpha but if anyone wants to try it please reach out; email's in my profile.
You plan on turning this into an actual service? BTW looks nice, I'll check it out when I get home. I like that your able to do this by your self but Travis CI can't with significantly more resources then you.
Yes, but I'm taking my time and rolling it out slowly. It's used in production by a handful people for various projects, but it's lacking a lot of polish.
I'm still assuming it's been less then the 4 years since FreeBSD support was brought up and the 7 years since Windows support was brought up on Travis CI's issue tracker. But either way nice work.
