Th short answer is no. AFAK your MBP only has one FW bus. IO HD uses this.
From the AJA FAQ:
Q: Can I use Firewire storage with my Io HD?
A: Yes you can however only if you install a PCIe Firewire card and use it for the Firewire storage.
Which you can’t do with a MBP. You could get an express card adapter for another FW bus, but then you might as well go ESATA.
hope that helps
