It looks good but it's not available from my usual sources for components either. Given the costs I'm working here I'm expecting shipping will cost about half as much as the entire project so I'm trying to avoid multiple sources for components.

On the upside I have found a p-chan mosfet from NXP with low RdsON. Only problem is I'm at max ratings for gate switching voltage. That's the other issue going highside, it's relatively straight forward to control gate voltage with reference to ground but not so easy with reference to Vcc, not when using an off the shelf driver anyway.

More research needed :-)
