Ok, so lets say that Bill goes off and implements feature "whiz".

Meanwhile, you're working on "bang".

I'm working on "wham".

I get "wham" done. Since I don't have commit rights, but I want to show 
it to you, I put up an arch archive on an http, ssh or ftp server 
(WebDAV is only needed for write access).

You decide you like it, but want to merge it into wham, rather then 
putting it in the main repository. So you merge from "wham" into 
"bang".

Later, you merge wham+bang into the main repository. Bill gets whiz 
done, but it turns out that it relies on some super secret Apple 
feature that hasn't been released yet. So he continually merges 
"wham-bang" into "whiz", that is he merges from the main archive into 
his local branch.

Meanwhile, we've all been able to checkpoint our work locally, without 
involving the "main" repository.

That's what tla would do for you.

  Note that "pierce", "bill" and "bob" in this instance could also be 
three different projects by the same engineer.

  Anyways, svn is an improvement over cvs, but since it doesn't support 
history sensitive merging, I would argue that branching ends up being 
broken.

  Hmmm... Doesn't .mac include WebDAV support? I wonder if we could use 
that as our host...
