When will we have Lens Cast Calibration in Lightroom

Question

Hi,
I do postproduction all the time for a couple of other photographers. They send me the raws and I develop them. My favourite tool to do this is Lightroom, especially since the quality improvement in version 3.
However, I often work on architecture shots that were done with a digital back on a technical camera (TC), mainly PhaseOne and Hasselblad backs. All these backs suffer heavily from colour casts when used with wide-angle lenses on TC's, due to the strong inclination of the lightrays on the sensor.
These images have to be developed in the raw software of the respective brand, CaptureOne for the Phase backs, and Phocus for the Hasselblads.
Both have a special function to analyse the cast of a separate image which has to be shot each time with a translucent white cap on the lens.
These casts are then perfectly filtered out, and one can carry on with the rest of the development of the raw file. But this has to be done within Capture1 or Phocus, 'cause you can't export a DNG with the lens cast corrected. You can of course export a Tiff to Lightroom, but then you loose the whole dynamic range of the raw.
It's this feature that I'm really missing in Lightroom. I prefer using Lightroom, because I use  the local adjustment (gradients and brushes) all the time.
None of this is possible in CaptureOne or Phocus, a shame really. I wrote to the developers of CaptureOne to ask for local adjustments and it took me 6 mails before the good man understood what I was talking about. Don't they look at Lightroom?
So Adobe developers, if you could add Lens Cast Correction (or Scene Calibration as it is called in Hasselblad's Phocus), you have the best RAW program in the world, and I can finally dish all these other brand-infected stuff from my hard disk.

What about this
Scenario
Take 2 images, from as close a standpoint, ie with camera on the tripod etc.
1 is the original image,
2 is the one through the white lens cap.
You now have the colour cast from centre to corners in the capped image as a reference to work from.
All that needs to be done - I guess in photoshop - is to remove the colour as referenced by the capped image from the shot.
Simple in photoshop - like everything is - a plugin / mask / reverse biased logarithmic flip flop or what ever.
The process in lightroom would most definitely be a develop setting - where one image would be the reference and this could then be applied to one or a selection or all the images.
As Ssprengel remarked, this is specalised and probably many people would not need it. Then many people did not want the lens correction, and the number of posts and discussions about that are rising most days.
Rob, one for your sleepless nights
subtracting  R,G,B on a  pixel by pixel basis from an image, very very simple to do surely....  I'm sure Pixelbound would be impressed, and another notch on your  bedpost of plugins for lightroom.
