DocBook on the Web

Reading Norm's latest post 
<http://norman.walsh.name/2006/10/30/openMind> I wondered, has anyone 
tried publishing straight DocBook on the Web? i.e. sending  real DocBook 
XML + (CSS | XSLT) to the client; not doing the conversion server side 
or earlier and sending HTML to the client? If so, what were your 
experiences.

My suspicion is that even assuming client side support there are several 
problems:

1. There are no straight CSS stylesheets for DocBook.

2. The XSLT stylesheets are too complex to reasonably render client 
side. They also likely rely on extension functions browser engines don't 
have.

3. Anything beyond an article is too large for one page, and it's not 
really possible to chunk pages on the client side.

Are these fixable? Is it worth fixing them? Or is it just that 
prerendering to HTML simply is the better option and we should stop 
worrying about it?
