Cool -- Nando had that on the wish list for QL for a long time.
Alternatively you could go with GNU R for which I have built some simple
prove-of-concept wrappers around a few option pricers; look for RQuantLib.

My very personal $0.02: I used to code a lot with Octave, but the things I
am interested in are really more data driven and data analysis focussed --
and I have come to appreciate the incredible power of the S language.
Consequently, I pretty much do all I do (apart from C wrappers and simple
Perl tools) in GNU R, the open source dialect of the S language.
As for S, I can only concur with the ACM software systems award to the
language creator John Chambers:
"will forever alter the way people analyze, visualize, and manipulate
data . . . S is an elegant, widely accepted, and enduring software
system, with conceptual integrity, thanks to the insight, taste,
and effort of John Chambers"

John Chambers is a member of the R Core group which is pushing GNU R to new
heights. Most statistical research pretty much happens there, as opposed to
the commercial S-Plus dialect. R is written in portable plain C with calls
to standard libraries as well as some specialised packages. R already has
some Kalman filtering in the standard ts (== 'time series') package, and
more in Paul Gilbert's add-on package dse.
That said, and reverting back to the original questions :), I once 'glued'
the parts I needed from the Fixed Income toolkit of the major investment
bank I was working for at the time to Octave. Worked well for bondmath and
all that. But some Octave internals have changed, so not sure how much help
I could offer you now. Come over to the Octave lists, I'm sure people will
give you a hand there.
Good luck, and keep us posted, Dirk
PS Incidentally, I am involved in the program for the upcoming 'useR! 2004'
conference in Vienna next May. If someone wants to do something with
R in a financial econometrics context let me know! More info is at
http://www.ci.tuwien.ac.at/Conferences/useR-2004/ -- maybe I finally
get to meet some of you fellow Europeans over there?
