I'll be going over a number of things, time permitting:
* memcached (in general)
* NorthScale's memcached Amazon Machine Images and Virtual Appliance
* moxi - memcached proxy
* memcached Functions for MySQL
I'll run a couple demonstrations with each, first simple memcached usage, then using two memcached instances through moxi, then I'll throw in using them with the UDFs.
I intend to see if the Boston MySQL Users Group would be interested in this talk soon as well.
