The prefix is not needed. It makes it easier, but is by no means a 
requirement, as long as you keep the unit names separate.

Compare

   Edit1 : myedit.tedit

to

   Edit1 : tmyedit

In the second case, you'll cover 99% of all cases.

If by any chance there is an overlap, then the first scenario

   edit1 : myedit.tmmyedit

is still an option.

I work 12 years with lots of libraries, and I have exactly once (1 !) 
encountered a problem with duplicate names; when Delphi introduced strutils, 
it clashed with rxlib's strutils, which was subsequently renamed to rxstrutils.
problem solved.

So namespaces: yes, nice to have.

But do they solve an urgent problem ? I don't think so.
