flesh out TODO re: AvoidDiskWrites

  - If the client's clock is too far in the past, it will drop (or

    just not try to get) descriptors, so it'll never build circuits.

  - when we start, remove any entryguards that are listed in excludenodes.

  . start calling dev releases 0.1.2.1-alpha-dev, not -cvs. Do we need

  o start calling dev releases 0.1.2.1-alpha-dev, not -cvs. Do we need

    to change the code in any way for this? Appears to be "no".

  - Remember the last time we saw one of our entry guards labelled with

    the GUARD flag. If it's been too long, it is not suitable for use.

      ORPort/DirPort.  It should support ranges and bit prefixes (?) too.

      - Parse this.

      - Relay this in networkstatus.

  - Have a mode that doesn't write to disk much, so we can run Tor on

    flash memory (e.g. Linksys routers or USB keys).

    o Add AvoidDiskWrites config option.

    - only write state file when it's "changed"

    - stop writing identity key / fingerprint / etc every restart

    - stop caching directory stuff -- and disable mmap?

    - more?

Future version:

  - Tor should have a "DNS port" so we don't need to ship with (and

    that it is able to rotate through. (maybe)

  - let each hidden service (or other thing) specify its own

    OutboundBindAddress?

  - Have a mode that doesn't write to disk much, so we can run Tor on

    flash memory (e.g. Linksys routers).

Blue-sky:

  - Patch privoxy and socks protocol to pass strings to the browser.
