Update: This installation process is no more necessary. The new suite has an one-click installer app.Please install Capture One and/or DxO before you install apHUB. The installer detects these programs and installs the approriate scripts.Anyways please read the "Please read before you start" file in the suite. It tells you about the few steps you still have to do manually and explains the additional scripts within the suite.
Using apHUB is very easy. It is basically just pressing a keyborard shortcut.
On my System:
Option+CMD C to send the pictures from Aperture over to Capture One.
Option+CMD X to send the pictures from Aperture over to DxO.
Option+CMD A to send the pictures from Capture One or DxO back to Aperture, replacing existing edits if possible.
Shift+Option+CMD A to send the pictures from Capture One or DxO back to Aperture, always creating new "versions".
I write "version", because they are indeed new masters in Aperture but they are linked to their original master in Aperture. You don't have to care about this, just think of them as "versions".
Setting up apHUB is a bit more challenging but you have to do it only once.
Do yourself a favor and download
FastScripts. It's free for 10 keyboard shortcuts but I'm sure, you'll buy a license once you got the hang of it.
apHUB has been streamlined to make the roundtrip as seamless as possible and having to navigate menus to send the pictures back and forth IMO doesn't make sense. While you can use apHUB without FastScripts or even create your own Applescript shortcuts workflow with Automator actions i.e., this instruction assumes, you have installed FastScripts.
Download the ZIP file from the downloads category (when it will be available) or the beta-tester category (ask for a beta-tester account, if you are willing to participate).
Extract the ZIP to your desktop.
You will see a folder like this:

Move the files to the locations indicated by the red arrow. If a folder doesn't exist on your system, create it.
Open FastScript Preferences and set the keyboard shortcuts as shown in green above (or use your own).
For Capture One:
Open Capture One and create a new session document
(important, it must be a session!). I suggest you name it apHUB but you can choose whatever name you like.
In the Finder ctrl or right click on the Output Folder of the newly created session and choose S
ervices/Configure Folder Actions.
Choose
Capture One -> Aperture (FolderAction) from the popup. Check
Activate Folder Actions, if it is not checked already.
For DxO:
Create an Input and an Output folder somewhere on your harddrive.
In the Finder ctrl or right click on the Output Folder you've just created and choose S
ervices/Configure Folder Actions.
Choose
DxO -> Aperture (FolderAction) from the popup. Check
Activate Folder Actions, if it is not checked already.
apHUB should work now in its default configuration.

Happy apHUBING

According to apHUB it uses nothing inside Application Support.
I don't get how to assign a fastScripts keyboard shortcut. If I click on the fast scripts menu bar icon I can go to preferences. The choices in preferences are:
1) script menu which doesn't appear to have a keyboard shortcut edit option
2) Script Shortcuts which displays the path to a folder titled /library/scripts. That contains a list of several categories of scripts including color synch; folder action scripts; folder actions and several others. Folder Action scripts lists several scripts with no short cuts none related to Capture One or DxO as does Folder Actions. There is no apparent way to add a new script or to edit shortcuts for the script.
3) Registration - without documentation that isn't appealing
4) Software update
I am unsure what I am missing but I don't see a way to generate a keyboard shortcut and point it at a script within FastScripts.
