Hi Dmitry, softraid(4) could certainly use some work, including RAID10 support. You're welcome to try and add another discipline, and maybe fix a bug here or there while doing so :-) I can't help you with the details as this is not my area, but feel free to contact me on irc or via email for pointers in the right direction.
