- Add all RPMs (by default) to a DepsQueue.  All deps will be looked
  for in this queue, which will have the latest versions of all packages
  even if they have been ignored or in an Install(No) block.  It will also
  cache provides entries as they are retrieved.  
- Have special blocks (for the actual RH release) that will only be checked
  once for the dependency cache.  Maybe have a range of options for how often
  a deps-only block is checked... or maybe how often any block is checked?
- For a cluster situation, I want to have some way of storing the
  commands you run in interactive mode and pushing those commands out to
  the other nodes in the cluster.  For example, you enter interactive mode
  on the master and tell it to "install Omni-*" in order to satisfy
  dependencies for 'printconf-*', then I want the slaves to do that too
  (if so configured).
- In the long-term, I would like to interactively download
  dependencies that are not in the queue... possibly integrating with
  rpmfind, which does something like that (I think).
- Find some way to page through lengthy output (like the list command)
  i.e. list | more
