.. as well as help 'blind' these transactions to later log analysis
(depending on what they do with their internal logs).

Indeed.  Note, however, an interesting convergence property here, for
the practical user:

Say I'm selling something on 'bitbay'.  Bitbay offers me two kinds of
accounts: either immediate transactions to the bitcoin network, or an
internal/affiliate 'Bitpal' account, with a running internal balance and
aggregate external settlement transactions. 

I need to decide whether to trust the Bitpal exchange, both as a
holder of credit and potentially also as a privacy-blinding service,
presuming they claim to offer this value-add. Fine.

However, in practice, both mean I need to wait some time for my money,
even for the "immediate" transactions, until a sufficient consensus of
conmation blocks comes in.  So on the face of it, there's little
difference in my process for deciding when to ship my paid-for
product.  The only way to make it go faster, where that matters, is to
trust the exchange's internal accounts - that is the service they
must offer.
