Tranfer between iMac and Macbook?

Is there a way I would be able to connect my Macbook with a friend's iMac in order to transfer a large number of files to my MB? About 70GB worth? Ordinarily I would just dump his files onto an external HDD then transfer to my Macbook, but alas do not have access to an external HDD present.

Any ideas?

Use target mode. Connect both system using a firewire cable, Then reboot the system with the data to be copied holding down the t key. You should see the firewire logo in that system. On the other system you should see a new disk icon on the disk top. Now all you need to do is locate the data you want to copy and start the copy process.

Thanks
