many smart people i know actively avoid knowing the details of ill-conceived
and archic technology.  :-)

... how did i not find this solution? probably because i wasn't familiar with 
what the perms should be. it's 100% reproducible, anyway, i'll go pester 
p9p-dev.

This is obviously some strange usage of the word

just change the permissions on /dev/ptmx back to g+w.  in fact,
since you have a case narrowed down, it might be easy to find
& fix.  ☺

I think you echo all our thoughts there. As to implementing Plan 9's keyboard 
handling, am I right in assuming you mean for the purpose of writing programs 
for such a clean interface? If so, you might want to try linking with the 
plan9port libraries. Alternatively (and probably better) just write for Plan 9 
and import your Linux file systems. Drawterm and 9vx provide very easy access 
to the host's files and u9fs isn't far behind. Almost all the editing and shell 
operations I do on my Linux box these days are done via drawterm, the only 
exception being root-owned files.

By the way, if you run p9p acme on Linux as root, don't use win. The pty 
subsystem crashes or something; you have to reboot before you can open any X 
term. :D
