Just to continue the thought process, I am thinking of a button under the "More Search Options" check box that says "Auto-Download". You hit this button and what appears to be one download starts in the download monitor. This download goes through all of the cycles previously described using the conditions that were set when the "Auto-Download" button was hit. (it does one search, attempts to download everything one at a time, repeat) Several of these auto-downloads can be run at once.

If someone could give me directions on how to build the full limewire w/ gui with project builder (Mac OS X) I might try to implement this myself.
