I much prefer your CVS layout to the source release layout.

Here's my ideal source layout (which assumes the CVS layout is used as
the source release layout):

[current content of daemon directory]

Leave the daemon source at the top level (as it currently stands in
the source release); the C libraries provide a client implementation.
Directories for other client implementations leaf out from there.
Java client and app code is mixed in the spread/ package tree (used in
most projects), but could be JAR'd using different build targets (if
desired).  This layout makes the assumption that the only
implementation of the daemon is in C.

Regardless of which way the source tree is layed out it'll be nice to
have those build files work in the same fashion between CVS and
release layouts.

                            Thanks, Daniel

p.s. To preserve CVS history, the content your CVS data
files/directories can be moved around on the file system (just make
sure the permissions remain as they were before).  Warning: this hoses
