some witterings about where we are

Things that still need to be done

* Remove the global 'user' variable in the client

  - this needs to be replaced with looking values up some other way

  - should fetch a copy of the user record (ala who list) from the 

    server and keep it cached. 

  - update cached record whenever you get an IPC_CHANGE update

* put in some proper encryption / auth mechanism so we dont wind

  up potentially passing plaintext passwords around

* check that the server is now logging all the things a user

  says an does, client shouldnt really be logging anything much

* have server perform the mwuri lookups and logging

* final big change would be to have the server do the bbs features as well
