I notice when you tag something byte[] as XmlAttribute the result is base 64 encoding inside
the attribute. I presume unmarshalling does the right thing. 

How about:

{code:xml}
<CellSet>
  <Row name="row name">
      <Cell column="test:c1" timestamp="1128765413420141">
          VGhpcyBpcyBhbiBleGFtcGxlIHZhbHVlLgo=
      </Cell>
  </Row>
</CellSet>
{code}

along with protobuf changes to match this structure?

One thing I can't figure out how to do is specify alternate encodings for cell bodies. For
example, before this was allowed:

{code:xml}
<Cell column="test:c1" timestamp="1128765413420141" encoding="base64">
          VGhpcyBpcyBhbiBleGFtcGxlIHZhbHVlLgo=
</Cell>

<Cell column="test:c1" timestamp="1128765413420141" encoding="plain">
         This is a plain text value!
</Cell>
{code}

which can represent significant savings if there is a large amount of plain text data to transfer.
It's arguable if this is really needed. I just mention it.

> Improve the semantics of the REST interface: more metadata operations, bulk updates,
protobufs (if Accept equals "application/x-protobuf" for GET or Content-Type equals the same
for PUT or POST) instead of multipart/related (which is not supported now anyway) etc. for
general efficiency and support for queries or scanners that return multiple KeyValues. 
> I am working on a proposal.
