My initial thoughts concerning the purchase were absolutely negative, as shown in my posts above. However, something I thought about yesterday on my way to work... Google has shown interest in the HA market (a la Android@Home), and this adds another feather in their cap to integrate and possibly produce a great HA solution if that is indeed their ultimate goal.
As with any powerful, yet small-group nature'd product, the user group behind Sage definitely added benefit to the overall experience. I could only wish that this doesn't go away, and somehow they embraced the community for input. However, with such a large corporation making the purchase, it seems inevitable that everything will be brought in-house and there will be little, if any, further development as had been done in the past.
As mentioned above, CQC is another program that is in this niche market and 'feels' very similar as far as user community, etc. I know Dean has been through some struggles this year with CQC, but could only think of a pipe-dream-type world, where Google put together a single integrated system that really capitalized on all of the technologies out there and to tie all of them together in an elegant manner. If this were even a possibility, I think it would take a lot of work to really map everything out, and Google would certainly need the assistance of those who have been leading the efforts to make it happen, and this may be where they are going (??).
Other than the above mentioned concerns, I also worry that Google is going to frown upon home based servers and try to move everything to their cloud. Until ISP data rates are drastically increased, I personally dont think it's a viable solution. Yes, it's close, but if they did support ripping if your own movies, the time it would take to upload 6-7GB (DVD) or 25GB+ for a BluRay would be ridiculous. The only way I see that working is if 'Hollywood' got involved and allowed a better solution; such as possibly having all of the movies already on the cloud, and you purchase the 'license' to access is.
LOTS and LOTS of speculation for now, but I'm semi-excited to see what they are able to put together, while hoping they dont kill Sage as others believe may very well happen.
