Currently, it's not on our list of things to do. There are a number of
reasons why it would be better to use Zookeeper here than to try and
build it into HBase.
That said, I think you could get everything you need if you tried
Zookeeper, using that to acquire locks on the row you need a
transaction on. It's supposedly very high performance and supports
your use case precisely.

startUpdate is deprecated in TRUNK. Also, it doesn't do what you are
thinking it does. Committing a BatchUpdate is atomic across the
whole row, however. There is currently no way to make a get and a
commit transactional, though there is an issue open for
write-if-not-modified-since support. If this is something you need
we can talk about how it might be supported.
