Please yes. Any meaningful competition to Netflix for a native(ish) video service client on the PS3 would be awesome. In Canada there is currently no other comparable streaming option available and Netflix seems to have very little impetus to deliver a decent GUI (it seems their goal is to limit utilization based on the reduced functionality of more recent clients and posts to their dev blog).
Not sure how Hulu compares for you US types but another player in this space has got to be a good thing.
