Nice to see you are interested in ViTables. Although there has been
some delays (sorry Norbert) the project is progressing well, and a
beta version will hopefully be available next week.

As far as HDFView is concerned what we are trying is to make a tool
that cover its deficiencies in managing large datasets.

As it happens with the entire PyTables family, ViTables is intended to
manage really large datasets in a fast and comfortable way. This is
its main strength. For example, with ViTables you can open a table
with 100 millions of rows in a few tenths of second, with very low
memory requirements. HDFView simply cannot do that as it consumes tons
of memory.

Included features in the beta version will be the ability to create
object trees from scratch (that later can be fed with data from
Pytables scripts), object tree edition capabilities (what includes
moving nodes from one file tree to another one), and attribute edition
capabilities.

Another distinctive feature is that, once CSTables (the client-server
version of PyTables) will be out, ViTables will be able to manage
remote PyTables files as if they were local ones.

Other features include ease of configuration and an integrated
documentation browser. At the moment ViTables is focused on browsing
data more than on editing data, but edition of leaf data can be added
on future releases if a demand of such feature exists.

And last, but not least, ViTables can be used as our starting point to
develop customised graphical tools to handle HDF5 data.
