Hm, after cursory examination (the code is here and instructions here) I think it's quite doable. Token generation and emailing are distinct, separate steps, and the database schema is already designed to hold multiple concurrent elections.

The only modification needed would be to make scripts/mail-instructions.pl grab all elections' tokens and insert them in the template (in fact it already partially supports multiple name/email/token substitutions into the same template). Then you'd just run scripts/create-tmp-tokens.pl 9 times to generate the tokens and scripts/mail-instructions.pl once. It looks like about an afternoon's work, I'm pretty sure the maemo.org maintenance budget can handle that, especially since we didn't have a council election ;-)
