I agree that this is the key issue here. 
I was hoping that google somehow was able to expose the tags in the "All
Mail" folder, like the headers that are gmail specific: X-pstn-nxpr and X-pstn-nxp (which contains a
hash) for instance.

ah, I have the ubuntu version,  will update to git soon.

now using gnus still, b/c notmuch does not build for the N900 (bummer)
