Brian, how can you predict which area code prefix is going to be called and which prefix to add for each of the local called numbers ?. its quite possible the last 7 digits could be available in 1 or more area codes that are local ...Thoughts??

I haven't used them yet, and I'm not yet convinced that they will be very useful in a production environment. Having said that, I'll tell you have that I have configured this exact setup (but without local route groups) for a client. It was actually quite easy. Put the seven digit patterns in the "Local" partition (9.[2-9]XXXXXX). Put the "11" digit pattern in the "Long Distance" partition(9.1[2-9]XX[2-9]XXXXXX). Same as normal. The only difference is that when we send the local call, we strip predot and then prefix 1XXX (where XXX is the local area code). So, if the local area code were 408, and someone who has the CSS with the local partion in it dials the local number 95551212, we would send it out to the telco as 14085551212. If they dial 914085551212, but they don't have the LD partition in their CSS, the call would fail. Now, couldn't you do that using local route groups? I would imagine it would work if the gateways were H.323. Just make the translation in the dialpeer instead of in the callmanager. Am I way off?

If you are designing a dial plan where the PSTN requires 11 digits for both local and LD, what have some of you done to apply calling restrictions so that certain phones (lobby, breakroom, etc.) can only dial local calls. We don't want to use any long distance access codes such as FAC or PSTN codes. We are looking at using the Line/Device approach with local route groups. The only way I see it is to know of every area code/prefix that is considered local to that site, then create route patterns based off of those. This would be tedious work as new prefixes could get added and you may not know about them.
