[Ti] Airport backup?

[Bradley Ellis]

Hello all,

There may be a better place to pose this question - please advise if  
that is so.

Is there a way for me to "hardwire" my LaCie ac-powered firewire hard  
drive to my Airport Extreme base station (or Airport Express) and  
have this hard drive available wirelessly for access via my wireless  
Ti PowerBook (for back-up, etc.)?

Thanks in advance for any help or direction anyone can offer.

Sincerely,
Brad
