Export locking sheet to Excel

[Klokan Petr Přidal <klokan klokan cz>]

Hi,

I'm really interested in repairing open Bug 330129 – Export locking 
sheet to Excel - http://bugzilla.gnome.org/show_bug.cgi?id=330129
(Maybe including validation which seems to be correctly exported only in 
Excel97+ export).

Is anybody interested too?
Is anybody working on it?

Is that hard work for somebody who know the Gnumeric infrastructure?
How many hours of work you expect?
(I can sponsor such patch maybe if it will not ruine me :-))

I think all what is need to be repaired is described in the document:
http://sc.openoffice.org/excelfileformat.pdf

Unfortunatelly I'm not Gnome guru, and I have not studied all the GSF 
and Gnumeric sources... etc. ;-)
I would like to repair it myself if there is no other way, but I'm sure 
it will take me much more time than it will to somebody with experiences.
Anyway: Can you help me on IRC with that if I reach some obstacles (I 
promise I will not bother you every 5 minute :-))?
Where and what I should start to read - I mean any developer 
documentation available? Or just source? Which file to start with?
(I expect to work on it during weekend, maybe next week)

Thanks a lot for any advices or answers
