Moca network?

I am just looking into Moca and would like to hear other peoples experiences.
Does it work well?
What problems could I run into?
There is no cable service in my area but a lot of DirecTV and Dish.

I use it and it works great. Maxes out the 100 Mb/s Ethernet, and my tivo boxes support it natively for remote streaming and what not. Probably doesn't matter since you don't have cable, but you would normally want to put a moca filter on your incoming service so your network isn't exposed to your neighbors.
