VS-700R in standalone?

Hi!

I'm searching options for my girlfriend to make her the ultimate keyboard/piano live/studio rig (I know it's subjective but it's not the point here). 

She's a Roland user since her first keyboard (a JV-80) and we've found that Roland products is indeed what matches her need best.

1st: The piano task will be accomplished by a V-Piano (she's helpless with her piano sound and this one look awesome!)

2nd: The synth is a V-Synth GT (INCREDIBLE!)

3d: All orchestral parts would be covered by a Fantom synth and a Cakewalk A-800 Pro controller.

So I tought the VS-700R could handle that job instead of the Roland rack Fantom XR.  The VS cost more but gives and incredible audio interface and the possibility to add an ARX card, a collection that will continue to grow (we both hope the next release will be a strings expansion...!) and which is awesome instead of the stagnant SRX serie.

Money is not an real problem since each piece will be bought one at a time.

So the main point I need to know is can I use the VS-700R to easily mix it's inputs, edit Fantom patches and record to Sonar (LE probably) without the VS-700C?

With only a laptop?

Without any computer (standalone)?

With a MAC laptop?

Thanks!

PS. Don't hesitate to tell me if I'm not clear enough!
