Speaking of remote control issues for you guys that maintain systems like these. If you have remote access via the Internet check this little box out: http://www.headend-remote.com/
It's a great concept to be certain, but most of the nursing homes that are/have recently put in SD TV systems don't even have Internet, or only have one tiny pipe shared by the admin. They wouldn't pay for these boxes or for an Internet connection for them. I can't stress enough how tight they are with a buck!
The folks who go with the HD systems often have Internet, which can make managing those systems (well, the Com1000 systems, anyway) a breeze. The LGs still require local access unless they buy the Pro:Centric server also. But the LG racks can be quickly set with a computer and a TTL cable.
