[TriLUG] non-netsol registrars with non-web interface?

[Rodent of Unusual Size]

i may have asked this here before, but..

netsol is not my favourite bunch by any means, but one thing
i like (that they inherited from the internic) is the ability
to do registrations and make changes using email authenticated
with pgp signatures.

unfortunately, they appear to be the *only* one with this
capability.  at least as far as i've been able to find.

does anyone have any experience with any other registrar
which provides an asynchronous semi-offline service like
this?

tia..
