Christian (chr.tx0.org) reminded me that moles (executable scripts for the
Bucktooth Gopher server in use on SDF) could be useful for interactive
Gopher applications. It's somewhat abusing the notion of searchable indices
(Gopher type 7) by using the search string as a generic input to a string.
I have put up a demo application that corresponds to a chat - chag!
Here's the current version:

#!/bin/sh
# gopher chat demo (2009 Yargo Bonetti)
chag=/ftp/pub/users/yargo/glog/chagfile.txt
tmp=$chag.tmp
echo "[..${REMOTE_HOST#???????} `date -u +%y-%m-%dT%H:%MZ`] $@" >$tmp
cat $chag >>$tmp
head -n 999 $tmp >$chag
: >$tmp
echo $chag:
echo
cat $chag

..and yes, there's no locking and stuff for the moment, so if the masses
start using it in parallel, the script may fail, I now. It's a demo. :-)

Actually, this could be modified into a reply script for glog entries.
Maybe one could generate a symbolic link to the script with a name
containing reference to the glog entry, so that the script knows where
to append the reply. Or something different..? Have to think about it.
