Long Firewire Cable Runs

Greetings All,
Thanks in advance for any assitance.

I would like to move my mini about 25' away from my apogee duet and the rest of my system. A little research points out that 15' is the maximum distance for firewire cabling.

I'm considering using a powered hub or repeater. Is there any reason not to take this approach? SHould I be concerned about drop outs?

With Thanks,

David
