Even with our limited userbase, I didn't want to get into having to
maintain pre shared secrets with all of my users. I also wanted to have
support for as many clients as possible, and while I've seen reports of all
the OS's I mentioned working with FreeBSD IPSec, I'd describe the
experiences "painful" at best. But I digress :)

Is tunneling PPP over SSH considered a port forward, though? If it's not,
how would one go about disabling the Nagle algorithm in the ssh client? I
don't see anything to that affect in the man pages. Or, do I have to do
that at compile time...
