Unlikely in the short term. I made this driver for my employer, I think there might be reluctance about releasing it to the public. On one hand this would most likely increase the quality of the code, on the other hand this might hurt us in helping competition. I know this would be cool since there are people out there who would like this feature. Right now the driver needs to be tested further. The number of machines on which it has been tested is ludicrously small (one virtual machine, one laptop). But anyways the thing that will prevent the driver from ending up in the tree is that my coding style doesn't respect FreeBSD rules (omg!). For the rest the driver correctly interfaces with GEOM via the disk(9) routines and the read and writes are queued in a working thread.
