Even though it probably does not bother you, have you been able to find very flexible USB leads ?
Best source for those is the retractable usb cables you can get from ebay for almost nothing. Remove the single screw in the middle of the winder under the label, and it'll come apart (probably with a 'sproing' and a lot of little ball bearings flying everywhere) leaving you with a premade remote cable made from earphone wire.
They're *really* not much good for anything more demanding than a USB 1.1 mouse or keyboard (which is why they're so cheap, and why no other usb cables are that thin or flexible) but they work brilliantly for our purposes.
