When I worked with the Aptus22 there were virtually no color casts. A file shot tethered or to CF card could be opened and converted in LC8, LC11, ACR, Lightroom, Aperture, Raw Developer, and so on.... with no preliminary conversion or correction. The back can be used tethered with the current software as well very easily.
The Phase LCC solution only applies corrections to the output files, the RAWs are never touched. Phase one RAW files shot on an Alpa or similar cannot be processed in any software other than Caputure One Pro. The new Capture One Pro 4 will possibly have the ability to output DNG files with the LCC applied and make it possible to use other software, but that is still on theory. I expect to see C1 Pro v4 by 2015 (Although Phase says it will be out next spring).
Many months ago the DNG files that were output by the Brumbaer converter could not be processed in the Sinar capture software. So, an investment in the Sinar back for architecture shooting may mean that you don't use the Sinar software, but instead choose between other RAW converters. I think this is changing soon, but I don't know if that in 2 weeks soon, or in 18 months soon. Most of the commercial architecture photographers I know work tethered to a laptop. Although I can work by myself just viewing the back of the camera, I prefer to show the architect, art director, magazine editor, or prop stylist the images on a computer screen.

stunning your long time exposure, but it looks to me as if there would be color shift from left to rigth. something looks strange about the colors, maybe its just me.
for noise i would appreciate to see a 100% crop of it, its possible? but its clear hat the phase backs do a great job with long time exposures.
i did also some fullmoon shots and they have an amazing atmosphere,- but i used the canon for it. do you have to wait 20 minutes after the exposure for the black reference shot if you use the PO?
about the dalsa 22: in the time i was working only with the eMotion22 i didnt used white references,- although now i see that this back looks even better as it did before, if i apply the white reference to the dalsa22 also.
yes,- i forgot to work with capture and i dont see a reason why i should do it. lightroom, photoshop or iridient have so amazing raw converters that i dont care at all if i can open my dng files in capture software.
funny ... all architecture photographers i know mostly work untethered,- at least for exteriors. some work tethered for interiors, as i do sometimes too,- but really sometimes. you do the same, eric as you describe it, isnt it?
and yes... thats theory that the white references can work if you one time have shot them, stored them in a "white file bank" and than you apply them to your shots which you do later. in fact you have to write down in this case every millimeter of movements and which aperture you used .... its much more work than to shoot a new lcc shot and apply it. and soon you will see also that this method sometimes works and sometimes not good enough.
although with the aptus22 or the emotion22 there is no urgent need to shoot white files, with the P25 it is. as far i know this back shows extreme color shifts with movements.
