Topic: macbook pro + HDSPe ExpressCard MADI + external converter via MADI

i have the possibility to buy an DAD AX24 with MADI interface inside.
i want to connect to the macbook pro buying the HDSPe ExpressCard MADI.
i would like to know if:

A) HDSPe ExpressCard MADI can be utilized with all the audio software as i made with fireface UCX. i utilize audio sequencer, but also software of acoustic measurements as REW and software of sound design as CSOUND and MAX/MSP

B) about latency, is it good as usb RME fireface cards?

C) are there things with FIREFACE that i can't make with MADIFACE?

Excuse for the simple questions, but i m new to MADI.

thanks Alessandro.
