Litecoin adoption has been suspended for now.  Given the amount of DDoS activity BTC Guild already receives, adding Litecoin is just another reason for botnets to attack.  Litecoin is already seeing a surge in botnet activity.  As BTC difficulty shoots up, Litecoin is going to be completely dominated by botnets due to being "CPU friendly".  The relative power of CPU vs GPU on Litecoin is very favorable to botnets.
