Remotely destroying all data on a laptop is reasonably easy to do thoroughly, with an EMP. It is somewhat messy, though; there is collateral damage.
If you want something more "surgical", you can destroy data remotely, subject to the following caveats:
As was pointed out, disk encryption can make this "wiping out" a moot point, so if you fear that your laptop may be stolen (but is still in your possession now), then you can install TrueCrypt with full-system encryption. Typing the password is then necessary to boot the machine up, and make sense of any byte which is on the disk. Therefore, assuming the laptop is shut down, not merely "sleeping" or "hibernating" at the time it is stolen, the data is safe and no longer requires any form of "remote deletion".
You could encrypt the whole disk with TrueCrypt and a very long key, leaving only random data when shut down. But that's a workaround, as data stays and could be read a few years later when a smart guy finds a flaw in the encryption algorithm...
