33 * - There is a race condition when two threads try to read from the same
34 * SMB handle. Either we need to lock the SMB handle for the time we
35 * use it in the client, or do all reading and writing to the socket
38 * - Each new handle opens up a new connection to the SMB server. This
39 * is not ideal, since operations can be multiplexed on one socket. For
40 * this to work properly we would need to have some way of discovering
41 * connections that are already open.
43 * - All access is currently anonymous. Password protected shares cannot
44 * be accessed. We need some way of organising passwords, storing them
45 * in the config file, or putting up a dialog box for the user.
47 * - We don't deal with SMB dialects at all.
49 * - SMB supports passing unicode over the wire, should use this if possible.
51 * - Implement ability to read named pipes over the network. Would require
52 * integrate this code with the named pipes code in the server, and
53 * possibly implementing some support for security tokens.
