Why do you need this: I want to get a new public IP address everytime I reboot the router in order to (for example) bypass the megaupload restrictions etc
Thanks
Only the far-end equipment of your ISP sees MAC.
Is "megaupload" an ISP "sales phrase", or a website?
If a website, changing MAC does nothing.
So you're actually tying to force your ISP to issue new IPs to you?
IPv6 or IPv4?
(You don't have to change MAC to get a new IP address for IPv6)
(and doing that via IPv4 without ending the lease may cause other issues with your ISP - that they'll eventually trace to you, and not like!)
also, if it's a website - @psherman notifying a mod, because asking how to violate terms-of-services, etc. is not allowed on this forum

I would like to automatize the process.

Why do they need to see my MAC?
Because you want Internet (i.e. ISP connection).

So, if i understand right, it's like this:
My device with MAC --> asking ISP for IP --> ISP gives IP --> MAC is now hidden by IP and websites I visit will only see IP ?
No.
MAC- Layer 2
IP - Layer 3
(This is not OpenWrt-specific.)

Just do a bash script to randomly modify the mac and put in /etc/init.d and call it from /etc/rc.d (like all any other init script). Use the $RANDOM variable of bash scripting.
Some ISPs change the customer public ip address when the mac is changed (they have semi fixed ip address). And I guess that's the reason of he want to do it, he want to create a random mac, to get different ip address from his ISP each time and that way he can access to certain web services who limit access by ip address.
