yep, I think it should have a little protocol where you write
"server:share:flags" to the socket and read back a password. flags
would say whether you wanted a lm-hashed password.

root can _always_ get the password. They just need to ptrace the
program that reads passwords. root is omnipotent :-)

it can't forget it, it needs to stick around for other subprocesses
who need authentication. smbwrapper makes a new connection for each

Would you be able to put some time into writing a prototype of this?
We will certainly need it before joe user can start using smbwrapper.
