Syncing the whole list

[lnjX]

I'd like to add the MUC / MIX search to Kaidan at some point. In that case the search requests of the users would all be sent to search.jabber.network. From a privacy perspective this is not so nice and it would be better to sync the whole list of channels and search it locally. I'm not sure whether this is a good idea though.

My questions currently are:

• Is the list small enough, so downloading it would be okay on every device?
• Is this scaling? What if there were 100k public MUCs or more?
• The list needs to be kept up-to-date on the devices: What about delta updates? (e.g. hourly diff files)
