Just my 2c.  If the traffic burden is excessive (which the hoster of the 
epg data needs to determine since its not a big deal for individual 
users) splitting the file could be achieved.  You could split the file 
by date and possibly channel.  Add a 'version' number which is iterated 
if there is a line up change from the previous issue.  Then clients just 
need to check what their version number is and if its lower than the 
latest it downloads it.  This could possibly be achieved with filenames 
containing version numbers or through an index file.
