Inferno has srv(3) which is the file2chan registry. The closest I can
get to the above, without writing a new limbo command, is
% load file2chan
% calc >[0=1] | {file2chan /chan/desk {rblock; putrdata &} {fetchwdata
> /fd/0} } &
% stream -b 1 /chan/desk
% echo 1+1 > /chan/desk
It doesn't really work as the plan9 one liner because file2chan is
binding a new instance of '#s' each time, so the /chan/desk file isn't
visible from other namespaces. If it used an existing instance it
would be. Also, putrdata might do multiple reads to satisfy the single
read from /chan/desk, which is why I'm using stream -b1 to read. So,
not a success, unless anyone can point out a way I missed.
