I use a PocketWizard MultiMax with cable #804-508(Motor Drive Cable) in one port and the Sync cable in the other if flash is needed. To trigger the camera and use available light you will need 2 Pocket Wizards(One as the remote and one attached to the camera). If you have a flash setup you will need 3 Wizards ( one as the remote one at the camera as a receiver and transmitter and one at the pack or a pack with one built in).
I think you can control how long the release contact is made with the MultiMax's but I have never altered this setting. You can download the instruction booklet for these units on the PocketWizard website. I think it covers this.
Yes, the same setup will works on my the cw winder also but you will need a different cable to attach to the bottom of the winder(I think it's #804-408)
