Yes you can think of it as a regular ole POT.
Internally its just a bank of resistors in a ladder (http://en.wikipedia.org/wiki/Resistor_ladder) which are switched in and out to achieve the resistance requested over the SPI interface.
Here’s a library that to use with this POT.
I wrote it when i used an MCP4161 in a project of mine. The chip featured on this page is a 4131 but the protocol is the same, so the library should work. If not, you could tweak it to work for both chips and submit a pull request.
No public wish lists :(
