Some Questions to Xanadu

Mr. Andrew Pam, and Others of Xanadu

I'm Soeren Grenzdoerffer, student of computer science and currently
working at
my diploma with the topic 'Ted Nelsons Xanadu'. 
Having read a lot about Xanadu some questions arose which I hope you can
me to answer:

Ted Nelson wrote in several publications that there is no censorship in
How will you handle forbitten topics like bomb-building or

In point 2o I read that 'every Xanadu service provider can charge their
at any rate they choose for the storage'.

Referring to education Nelson wrote that there will be no need for

I think that teachers and especially what their teaching can be

a certain degree. There will be no effective control over the Xanadu
in its function as a teacher, especially concerning political or similar
groups openly spreading their ideas ?

Without removing any document out of Xanadu how do you want to handle
'junk-information' ?

The WWW is already very big. Do you want to take over the Web with
Xanadu or do
you want to build your own system which will replace the WWW ?

h) The WWW lives from the many young people who don't want to pay any
Do you think that Xanadu will be alive like the WWW if you implement a
system ?

i) What are the reasons for Ted Nelson selling Xanadu to Autodesk in
1988 and 
rebuying it in 1992?
