+1 to following the "standard" layout (as Jim and I have discussed 
face-to-face):

   - "Explicit is better than implicit."  It is *not* a "dead chicken"
     to specify the trunk if that is what you want.

   -  Following the "currently-accepted best practice" proposed by the
      SVN folks may have issues (I don't understand why anyone would
      *ever* want to check out more than one branch at the same time[*]).
      Nevertheless, I think we lose if we buck the tide.

If we could get SVN to puke for checkouts which didn't specify a branch 
or tag (including the trunk), that would be even better.

[*] I will note that my Zope and CMF sandbox trees both have a structure 
like:

   Zope-CVS/
     Zope-head/
     Zope-2.6-branch/
     Zope-2.7-branch

   CMF-CVS/
     CMF-head/
     CMF-1.3-branch/
     CMF-1.4-branch/

So the idea of having a multi-branch "sandbox tree" is not repellent;  I 
just don't expect CVS / SVN to give me such a tree *by default*.
