I am curious about how people deal with the need to have a server to provide realtime updates to apps. When I first started to look at developing realtime support for my applications, I was hoping that I would be able to do queries to the feed targeted at particular stops. As this is not the case, I set about developing the apps to use my server.
I set the server up to download from the feed once per minute from 05:00 to 23:59. I was somewhat horrified to find that this amounted to about 5GB per day, which used up half of my monthly broadband allocation in five days! As this is obviously not tenable, I was wondering what other people do.
Thanks for any insight anyone can offer.
