encrypted IP tunnel for 2.1?

I have been looking for an encrypted IP tunnel for quite some time now,
but haven't been able to locate one.

While there seem to be numerous implementations of IPSEC, none of them
supports 2.1. CIPE is only for 2.0, too.

What is so difficult about 2.1?
I mean, 2.0 already is obsolete and will be really obsolete when 2.2
comes out, so I don't understand why the implementors aren't already
writing their code for 2.1.

Is there any encrypting IP tunnel for 2.1 out there that I missed?
Anyone care to comment?
