I implemented a similar model for our team, starting a few years back.
A little different structure: I made subdirectories under branches:
build, feature, archived, snapshot, and personal.

Checkpoint looks to be more like 'personal' than 'snapshot', though.

Snapshot is for exactly that: I've got a little python script, double click
to store a snapshot of your working copy. Gotta love the low overhead
branching. This policy has saved a few developers from disaster, both
of the "I just hosed my dev server" variety and of the "It was just one
last little tweak to the design, and now I can't figure out what it looked
like when it was working..." sort.

Personal, like snapshot, is excluded from commit emails. This is for
experiments, of the "Hmm... what happens if I... YIKES!!! Hmm... if
I do it again, will it still... YIKES!!!" persuasion. Hey, we're an R&D
shop, it happens, and having an audit trail (in the form of subversion
commits) can be very valuable when trying to figure out, for example,
details of a patent filing.

I'm not one of the people who counts here, but I can at least give an
endorsement from the perspective of "it works pretty well in the field".
