For now, I put a copy on 
ftp://quenix2.dyndns.org/FreeBSD/ports/distfiles/rc-1.7.1.tar.gz for the 
FreeBSD rc's ports. (just for the record)

Yesterday, I read the p9p rc man page and try it. I think that these little 
things are missing for me to use this shell as login shell:
- no history mechanism, like history(1) {- -p -- --p) that record commands 
in a $history file other than " "", wintext. This doesn't work in console 
mode.
- CTRL+f doesn't work in console mode (that's probably not rc's problem but 
keyboard setting in console mode).

For the rest, it look great.

I think that I'll try to do a fork of just the p9p rc with byron's history.
I'm not a programmer and I'll return to school Monday and I'll be very 
busy. so it could just be a vaporware.
