Storage is cheap and sooner or later you will get situation when something 
builds on all your machines but somehow fail on buildbot. In such 
situations debugging on buildhost helps.

Only results of builds should be provided.

I suggest doing few trees:

1. build from scratch (cleaned daily)
2. incremental build  (cleaned weekly)

This is how we do that in OpenedHand with Poky autobuilder. With buildbot 
software you can even see where it failed (with logs) and (re)start 
builds when needed (automatically or by hand). Buildbot can be notified 
from SCM when change happened so it will update and start incremental
