Right, but right now he's not putting anything in trunk.  So you have no 
hope of seeing anything.

And it doesn't matter.  If you aren't interested in what he's doing, 
don't look at it.  if you are, you are engaged anyway.

Are we talking about two different things?  Tim was saying that he 
wanted to avoid dumping 'junk' into SVN, yet wants to work more in the open.

Working in a branch is a great way to do it.

Which problem?

It's going to be the case that people will want to go off into a 
'corner' and try something.  it's nice that they can do it so others can 
  watch, help, participate, and still it is out of the mainstream 
codebase until that person or people want to bring it in (or propose to 
bring it in).

The merging would be their problem, just as it would be if they were 
just working at home or in the office on a private copy.

The benefits seem obvious.
