Yes - I only did it for that skeleton.[ch] but it might be an idea to move these
into their own svn directory and pull it with an external, so they
stop diverging.

While there, I'd also suggest it could be useful to have a function like

const char *find_header(const fishead_packet *fp, const char *name)

which would be used as:

const char *length = find_header(fp, "Content-Length");
if (length) printf("%d bytes", atoi(length));

as it's a bit unwieldy to use at the moment.
