I believe there's already people using consistent hashing on large
installs out there. As to the pecl/memcache client the code is not
released and still in CVS, but it is stable (and certainly ready to be
evaluated/tested), also a release is coming up so you can either wait
for that or build from source like

 cvs -d :pserver:cvsread at checkout pecl/memcache
 cd pecl/memcache
 make && make install

Enable it by setting an php.ini entry like

 memcache.hash_strategy = consistent

Please note that the consistent hashing implementation might still
change in the future when a standard is reached on the subject.
