The flip side of this would be incremental patching. Release a RTM version and 
then all servicing from there would be handled as a patch. The down side is the 
patches being cached over time would bloat the local system, so you'd want to 
consider doing a major upgrade every so often to clean out all of the patches.

I'm in process of getting self-updating bundles in 3.9 and I have a pull 
request for the core changes in place. If accepted, I intend on doing another 
pull request for WixStdBA to be able to self-update.  Note, I just completed 
the changes that were fleshed out but incomplete.  My implementation relies on 
the Update element pointing to an Atom feed containing a list of possible 
updates for the application.  It's left up to the BA to process each update and 
decide if the update is applicable or not.

If you create whole file patches then you might get that size issue, but 
patches can be smaller, the delta between the files.

I don't know if Burn can do that, but the question is: how does the customer 
know when to run it?  It's not too difficult for the app to call a company web 
service passing the ProductCodes and ProductVersions of what's installed and 
having it tell you if there are updates to download, but it does take that 
infrastructure work.
