I private WebDav server on my laptop would not do the trick, since the VPN I use (and most corporate provided VPNs) prevent split tunneling.

This means that to sync I would have to:
1) Drop VPN
2) Manually push a sync
3) Restart VPN

Additionally, my laptop rarely has the same IP address much less a DNS name. No, sadly a private WebDav server on my laptop is a HUGELY inconvenient way to sync OmniFocus :(

That's a far cry from the convenience of 'Omnifocus iPhone goes ahead and syncs in the background without having to think about it'.
