Hi,

with high interest I followed the announcement of ObjectHandler and
QuantLibAddin.

Got a couple of questions:

- I am not sure what Widget/ObjectWidget is supposed to do. Is it an example
for the usage of ObjectHandler?
Is it related anyhow to graphical representation (widget = window + object)?

- I don't quite understand the files interface.hpp/interface.cpp. Are they
supposed to define a general interface?
If so, why do they depend on ObjectWidget?

- Other than the current development build in CVS, I could not yet find a
released version of QuantLibAddin. Am I right?

- I am currently thinking about a (clever) way of remotely accessing QL
functionality (via SOAP). In the documentation/mailing lists
of ObjectHandler I read that this is also something you want to address in
the future and that you want to establish an XML-based
serialisation in order to achieve this (FpML). The problem I see is that for
remote access, a client-side proxy-logic is required for each QL class.
I assume that you want to achieve this client logic by various sub-classes
of Objects. Is that correct? If so, this would result in completely
"shadowing" QL classes with derivations of class Object. Am I right? If so,
isn't that a pretty cumbersome way? I actually don't know
any better way myself :(
