I'm not so sure we should discard these devices so hasty. Sure, with just some tens of bytes of RAM, you won't be able to implement 6lowpan-HC or DTLS. But as soon as we have some kilobytes of RAM (let's say 5kB as on some MSP430 motes), simple IPv6 connectivity is possible, if its functionality is well defined. As far as I know, current IPv6/6lo specifications do not consider unidirectional devices, but is there anything wrong in a simple sensor that just broadcasts (multicasts) its sensor values to a hardwired IPv6 address (e.g., ff02::2)?
