In this forum there is a thread explaining how to do Netflix on Honeycomb. Worked great on my Galaxy Tab. Search this forum for netflix.apk. Sorry I don't know how to do a link to it.
Yup..... com.netflix.mediaclient_246.apk works like a charm. I just renamed it to Netflix.apk. My Samsung 10.1 automatically found the Netflix logo all by itself. Now that's funny. Also pulled it from the Samsung infuse 4G market. Installed on phone. Wow! This is too easy. Just make sure you go to settings and allow non-market apps.
