I wouldn't get too hung up on lineups. Those are just collections of 
individual channels and they don't change very often, so they needn't be 
distributed in the same way as the program data itself. The data we need to 
distribute is data on what INDIVIDUAL CHANNELS carry -- that is, what's being 
shown on Sci-Fi next Thursday, what changes are being made to WGBH's schedule 
on Wednesday, etc. If the Myth box has lineup data, it will know it needs to 
download data on Sci-Fi, WGBH, or whatever, but you don't need to package all 
these channels together AS a lineup when you distribute them. In fact, that 
would be extremely inefficient, for the reasons you mention. This would be 
true no matter what the distribution method, although some methods might use 
a lineup name or code as a shorthand to deliver appropriate channel data to 
the client.
