It should not be too bad.... The web nodes must have (R/W) access to
the database server and shared files.
It is pretty inefficient if the web nodes are not collocated with the
proxy and/or database server.... But both treehouse and housetree have
plenty of memory. Aggressively caching should make this workable.
Memcached is distributed by design, but it has a weight knob which
can tell nodes to look only at particular memcached instances.
