Ramtron's FRAM?

Has anyone here used Ramtron's FRAM products? I'm looking at using thier FM24CL64-S, which is a 64k (supposedly) I2C, low voltage FRAM chip. I
have a few questions however -
Is it REALLY I2C? The distributor lists it as I2C, but ramtrons datasheet just says its an "industry standard" interface.
Under read/write cycles in the datasheet, it simply says "Unlimited" ... I know i sound horribly sceptical, but is this really the case?
Has anyone found a supplier that consistantly stocks these chips? Or has a stock of this chip in DIP? I'd like to breadboard a bit before i try pounding out a board, and i'd like to have a few spare.
Thanks! -Alex

Yes it is I2C but they also do SPI versions which are much faster and slightly easier to use.

The number of write cycles is limited to 10^12 times, which is 'almost' unlimited.

They have sent me samples, but it took ages. Farnell stock them in the UK.
The FRAM is great, I used it as scratch ram and it is very fast. No more worrying about write cycles!
