Are the brackup targets compatible?

Hi everyone,
I'm converting an rsync/rsnapshot backup scheme to use rsnapshot to
avoid the hassle/cost of moving files around (it's my Aperture Library
+ raw photos backup).
I'm doing a brackup backup to a Filesystem target now on the "backup
host" to convert the old backup to Brackup. I'm planning to then
change it to be backed up from the "real" host with the Sftp target.
Will that work? As far as I can tell from the code the chunkpath
method is the same. Anything else to look out for?
Three auxiliary questions:
1) Shouldn't we have a new release? The verify script looks useful
(to put it mildly).
2) I saw in the list archive that there were some (bad) gc bugs late
last year -- were they all sorted out?
3) Is there a practical way to re-use chunks from different backup
sources; or is that how it works by default? (Think backing up a bunch
of different boxes; many files/chunks will be the same). I was
thinking of using rsnapshot (like we do now) to a central host and
then 'brackup' that box; but that'd probably end up being too many
files for brackup to efficiently handle. (Our two rsnapshot backup
servers are storing ~1.5TB each with about 22M inodes in use each).
I guess the question is: How do you use brackup?
