FWIW, I took the time to sign up for web enabled content after receiving BSG season 1 on HD DVD the other day. Much to my dismay I saw zero web enabled content tied to the disc itself, rather just a few stock trailers for download.
My experience with the HD DVD "U-control" features has been seamless and I quite like the inline PIP interviews and featurettes.
I use a PS3 as my Blu-ray transport so I don't believe at this point I can even do the PIP commentaries and such, even if they did happen to be included on a given BD.
