Some thoughts about what we could re-use, either in principle or with the actual code:

- language translation system. It may be hackish but it is easier for non-technical people to contribute to and it works (tm)

- bodystructure response parsing. If I recall correctly this can be used almost as is

- other IMAP functions. Just going to have to see, my guess is most will be rewritten. If nothing else the existing code provides a basis for what we want to do. Just better this time :)

- site key mechanism using apache include. This is neat and gives us a bit more security.

- Surely more...
