First cut at revisitng the white paper

[David Hull <dmh@tibco.com>]

Most of the white paper actually looks OK.  There is some mention of the 
IRP, which will need updating.  The relationship between WSN and WSRF 
may or may not need cleaning up.

I would recommend putting some mention of the produce/deliver 
distinction in the whitepaper, along with a more detailed description in 
BaseN.

I would recommend switching the security considerations sections in 
BaseN and the white paper.  That is, the actual specs, particularly 
BaseN, should have the definitive discussion and the white paper should 
very briefly summarize and point to them.
