svn:externals has this property: it downloads source code from another
repository and prevents commits when committing the container.

This can be achieved as follows:

Say you have projects /foo-1 and /foo-2 where /foo-2 also is a
subcomponent of /foo-1. Now you can create an (empty!) subdirectory in
the /foo-1 module - say /foo/bar - and then switch the directory to
the /foo-2 tree. Now, commits to /foo/bar will be sent to /foo-2 and
commits to /foo-2 will be pulled into /foo/bar.

HTH,

Erik.

PS: Please start a separate thread if you want to discuss 'related'
stuff, or if you want to send comments on this mail. We need to keep
this thread 'clean' for the design discussion of depth
other-than-infinity checkouts.
