It seemed pretty easy for me.  Here is the relevant chunk from 
horde/config/conf.php:

# memcache
$conf['sessionhandler']['params']['hostspec'] = array('your.memcache.server');
$conf['sessionhandler']['params']['port'] = array('11211');
$conf['sessionhandler']['params']['persistent'] = true;
$conf['sessionhandler']['params']['compression'] = true;
$conf['sessionhandler']['params']['lock_dir'] = '/tmp';
$conf['sessionhandler']['type'] = 'memcache';

The lock directory will fill up with memcache lock files.  I wrote a 
script to clean these up, which we run once a day.  I have attached it to 
this message.

Don't forget that memcache has no security, so you'll need to limit which 
IP addresses can connect to the memcache server using some sort of 
firewall.
