Can I capture video via firewire to an external USB 2.0 powered 7200RPM drive on an iBook? Was wondering if there would be an issue with the DV format going through the USB pipeline.

video to FW and daisy chain it to a external HD via FW would be a better option.
But you can still try and see if there will be no dropped frames.
Most 3.5" Firewire enclosures will have 2 Firewire ports

I capture from minidv using my ibook's fw port then i use an external usb 2.0 hd as my scratch disk. I've never encountered any dropped frames so far.
vinnov4 is right. you can use an external usb 2.0 hd as a scratch disk. But you do need to use the firewire port to minimize the risk of dropped frames. I use a maxtor external HD in capturing and haven't encountered any problem at all. A Lacie external drive is good too!
USB 2.0 performance is bad, typically 20% worse than firewire due to over head. Firewire is a Peer to Peer technology, while USB is a Master slave technology, which basically means lots of overhead.
Get a firewire hub if your ibook doesn't have enough ports, otherwise daisy chianing should be okay. There are FW/USB2/SATA drive cases available.
You'll also get better performance by capturing to the internal hard drive if there is enough space. If there isn't you could upgrade that and put the old internal in an external case for general storage.
