The kolab project already store calendars and cards as e-mails. I use dovecot from few years using part of this project. They use libkolabxml who provide binding for encoding/decoding objects ; this is an approach with advandages and disadvantages ( an external library can be upgraded to reflect changes in object format) but i think compatibility is a good thing at the end. Maybe this could be pluggable to allow different xml formats, but I think all should be more or less similar. > > Some things I wonder about: > > - Maybe there is already some code out there that could be used to > implement it faster? - Maybe even use something else besides C to implement > it..

(There are a couple of reasons why they'd want to replace that. I think there are two parts of the project: object storage and protocol implementation. If you choose the kolab approach, the object storage part is already done :) > -- Mihai Badici[1] -------- [1] http://mihai.badici.ro
