Hey Dustin, here is a concrete example of what I am looking to do:
  - start with "v1" branch in Mercurial
  - commit a few changes into the branch
  - tag the tip of that branch as "build_50"
  - initiate a build off that tag as "v1.0.6 build=50"

I have a script that writes these strings into a header file, so that 
"--version" output of all binaries is consistent. The point here is that 
I want to have version information outside of the source in order to 
simplify merging. This lets me build multiple intermediate versions of 
"1.0.6" just by specifying the tag: build_50, build_51, etc.

So, my question is two-fold:
  a) does it make sense to produce release builds with BuildBot? (I 
think it does, but do people actual do that? If not, why?)
  b) how do I get the final installer/packages off the slave? (do I just 
scp or use NFS?)
