What I meant was, if I have the following structure:
trunk/ [svn:parallel:foo = ../branches/foobranch]
[svn:parallel:bar = ../branches/barbranch]
branches/
foobranch/ [svn:parallel:trunk = ../../trunk]
barbranch/ [svn:parallel:trunk = ../../trunk]
and I have a working copy somewhere in foobranch,
and I try to refer to "+bar", it doesn't work.
Hmm, what if there was a mechanism for indirection through
the properties on a different directory?
trunk/ [svn:parallel:foo = ../branches/foobranch]
[svn:parallel:bar = ../branches/barbranch]
[svn:parallel:trunk = .]
branches/
foobranch/ [svn:parallel:* = ../../trunk]
barbranch/ [svn:parallel:* = ../../trunk]
Now if I have 100 branches, then I need to set 100 dirprops on the
"trunk", but the other 99 branches just need the indirection specifier
to tell them "look at the trunk's dirprops for information about other
branches".

Perhaps make the property value look like a structured data type with
multiple subvalues, one of which says how many directory levels to chop
off?
trunk/ [svn:parallel:branches = (dir="../branches/*",chop=1)]
branches/ [svn:parallel:trunk = (dir="../trunk",chop=2)]
[svn:parallel:branches = (dir="./*",chop=2)]
foobranch/
barbranch/
Now "+trunk", "+branches/foobranch" and "+branches/barbranch" should
work from anywhere.
