Catching all errors (forms, site errors) and saving them

I'd like to intercept all errors on the site, including
CMFFormController errors, portal messages (even though they may not
necessarily be errors), and Site Errors.

The reason for this is that we have a C++ application that uses HTTP
to upload files to Plone, but we don't want it to parse the responses
looking for possible errors. We want to have a list of errors for each
ZopeId/Session. The errors won't be recorded all the time, just when
our C++ asks for it. For example, when the user uploads a file, but at
all other times it will not be recording errors.

We'll also use this error list for our XMLRPC calls that can result in
Site Errors. It will help our users undersand what went wrong.

Does this design sound good? Can you suggest a better one?

If everything is good, I'm currently looking for a good way to catch
CMFFormController errors. I've been reading the
code, and I think I'll need to override setError and setErrors. I'm
not convinced it's the best way, so I'd appreciate any help with this.
