Using nslookup (for example) through a pair of pipes works quite well
on NT. One should'nt dismiss the possibility of controlling an external
line mode program trough pipes so quickly, IMHO. That's my point.

It comes somewhat of a surprise to me that the concept of byte streams,
pipes and filters works better on NT than on Linux, in this specific
example.
