[9fans] 9p implemention using print() like formats for marshaling

[Steve Simon]

I am interested in a 9p implementation which used print()-like
format strings for packet marshaling. This was pre-9p2k and I
even have a vague memory that it was a student project, mentored by Rob,
though I may have made that up.

I found this code on the net a long time ago but I ahve lost the link;
does this description ring any bells with anyone?

Someone wrote a patch for libixp some years ago. The result was
public, but not exceptionally nice, as I recall. That said, I
suspect that I could write a nicer one in an hour or so, but I'm
not really sure it's the best approach.

For every complex problem there is an answer that is clear, simple,

I wasn't aware of the previous instance, but the stuff Anthony Ligouri
did for the qemu-based-9p server used this approach and I liked it so
much I sucked it into the v9fs kernel code but there isn't currently a
standalone library version of it (but it should be trivial to extract
it from the kernel code -- specifically:  http://is.gd/1q7hV ).  I
wanted to do a Plan 9 version using fmtinstall (or some variant)
because that should make it a lot cleaner, but never got around to
doing it.
