Hi
Are there any limitations? / Is it even possible?
I use DD-WRT and it is possible to connect a usb hub with four ports to it, and four discs.
You can also use the netgear firmware (but i do not know if it's possible to use a hub).
I have just bought this router and i'm very happy with it.
If you want to learn how to use DD-WRT firmware with usb discs, just follow this great tutorial posted by Peter:
