Ask HN: Any demand for C and system-level Unix consulting?

I'm currently working on my startup, but the time has come to pause and replenish my bank account. This means doing some consulting work.

I'm a decent C hacker, with system-level Unix and POSIX experience. In a past job, I wrote a large virtual filesystem plugin which runs on top of Samba, so I'm pretty qualified to help anyone who needs a custom filesystem (either networked with Samba, or local with FUSE). Other low-level systems projects would be fun, too. I have no experience with kernel-level code, but I'll happily give a discount to anyone who gives me the opportunity (or excuse!) to learn more about writing kernel modules, for Linux, any BSD, or Mac OS.

So, dear readers of HN: is there any demand for this skill set? I recently moved to the Bay Area, and I don't have too many industry contacts.

PS: YC companies get a discount, too. :)
