The West Coast Labs tests report that they successfully evade all known sniffers, which doesn't actually mean much since all it proves is that LocalSSL is sufficiently 0-day that none of the sniffers target it yet. The use of SSL to get the keystrokes from the driver to the target app seems somewhat silly, if sniffers don't know about LocalSSL then there's no need to encrypt the data, and once they do know about it then the encryption won't help, they'll just dive in before the encryption happens.
Absent any real data, crypto-dogma :-) says that you need hardware-encryption, physical sources of randomness, and all sorts of other stuff to really solve this problem. On the other hand, such hardware solutions usually come hand-in-hand with the whole hierarchical is-a-person "PKI" book-entry-to-the-display I-gotcher-"digital-rights"-right-here-buddy mess, ala Palladium, etc. Like SSL, then -- and barring the usual genius out there who flips the whole tortoise over to kill it, which is what you're really asking here -- this thing might work good enough to keep Microsoft/Verisign/et al. in business a few more years. To the rubes and newbs, it's like Microsoft adopting TLS, or Intel doing their current crypto/DRM stuff, which, given the amount iPod/iTunes writes to their bottom line now, is apparently why Apple really switched from PPC to Intel now instead of later. You know they're going to do evil, but at least the *other* malware goes away. So, sure. SSL to the keys. That way Lotus *still* won't run, and business gets done in Redmond a little while longer.
