Agreed, the MS 4000's split design helped tremendously with my ulnar nerve irritation. Keeping my wrists aligned with my forearms is the key. I've also been keeping an eye out for a mechanical keyboard in a similar form factor without any luck. The few alternatives that I've seen are such an enormous price premium over the 4000 that I can't justify the expense. Maybe I'll be the second contributor to your putative Kickstarter campaign.
