My inclination, based on what I've read and heard from others, is to say
"no".
But again, the best way to find out is to write the code. :\

Good question. I don't know the answer.
To answer the question you asked here...the answer is "no". There have been
MANY discussions of this in the past. Here's the lng thread I started
back
in May about backup strategies for ZFS pools and file systems:

But
Thank you David,
Thank you Cindy,
Certainly I feel it is difficult, but is it logically impossible to write a
filter program to do that, with reasonable memory use?

Hi Toyama,
You cannot restore an individual file from a snapshot stream like
the ufsrestore command. If you have snapshots stored on your
system, you might be able to access them from the .zfs/snapshot
directory. See below.
Thanks,
Cindy
% rm reallyimportantfile
% cd .zfs/snapshot
% cd recent-

No.
(Check the archives of zfs-discuss for more details. Send/recv has been
discussed at length many times.
