Is there any technical information available about Twine?  I can't find
out much information about it on the web site (http://www.twine.com/)
except that it just went into private beta (whatever that is), that it
is a product of Radar Networks (http://www.radarnetworks.com/), that
there are some patented web-related techniques incorporated in it, that
there are lots of press release on it, and that you are the first
advisor to Radar Networks.

PS: I note that some of the press about Twine mentions OWL, without any
     modifier.  Perhaps you should address your words to the Twine
     people as well.
