Thanks! Good luck with yours! It looks like an important contribution.

Agreed. I also hope this code runs on every NetBSD port, so that  
users of any architecture can collaborate with their Mac-using peers  
more easily.

Since our projects are both filesystems, I'll definitely be looking  
into your references, and I encourage you to peruse mine (once I put  
some up).

I have a feeling we're going to be sharing a fair bit of the same  
problems and questions throughout our projects, so I'm looking  
forward to sharing any insights as well!

I was actually considering this, but I wasn't sure if NetBSD allowed  
userland filesystems. If it does, a dynamically loadable/unloadable  
scheme similar to linux kernel modules would be terrific.

I read the comments in your blog, and it looks like there are three  
people now all working on new filesystems for NetBSD. Could this be  
the Year of the Filesystem? I'll have to check my Chinese calendar...

Take care,
