Enjoyed this talk, looking at the contributing factors to transaction
costs, it seems to me that linked e-triples offer a unique way to
bring down that value from the 50%.  Looking at each item you mention:

1. Low Transaction Frequency

This ties in with what has been talked about on this thread.  Put the
data out there and let the web do the REST.  So the first step is
marking up your data using good relations.  We then need mechanisms to
route interest in an good or service back to the producer, without
necessarily incurring a high overhead.  How do we do it (HTTPS POST?
SPARUL?  Web Forms?)  I think we need a proof of concept here.

I guess this also means building order and payment gateways on a
generic, and per business, basis.  Important also to obey regulatory
conditions and compliance.  This could be a lucrative business area
for anyone that is prepared to specialise in it, or perhaps some banks
are well suited to take this on.

2. Specifity

For this we need aggregators of the market, perhaps ad servers too.
Search will be a key application, so perhaps GR can help instruct
robots that want to crawl goods together and provide offerings in the
marketplace.  Yahoo is a good start, but we need many more hubs of
semantic goods, exchanges and marketplaces with innovative designs.
Semantic tagging will help with specific search, as will geo location
of the business.

3. Uncertainty / Opportunism

This was the area I found the most interesting, and also the area
where e-triples offer a unique advantage.  The concept of linking an
Agent to an ID (eg URL / email / #phone) is gaining traction these
days.  The great benefit of this is that it can be an entry point into
linked data and then proceed into trust and reputation, in order to
reduce the costs related to uncertainty / opportunism.  Ebay ratings
is a micro version of this, however imagine a global version, where
you can see reviews and ratings of a particular offering, and where a
business can see that a user is securely authenticated, and has a
reputation for making good on their transactions.

It may be interesting to mock up a system where a business can go from
marking up a product to receiving an order (perhaps by email at
first), and looking at how all the pieces fit together, then expanding
to other cases.  I havent seen the GR oscommerce plugin, so maybe that
does some of this already.  It may be interesting to work out how we
could do this technically.
