portable CRM closely integrated with portable thunderbird, repeat - portable thunderbird, not just thunderbird.

i am badly in need of this, as i am constantly on the move, & need a good crm, that can take addressess of my contacts, maintain transactions, as & when they happen, & keep reminders & todo list. contact addresses must have configurable fields, in addition to the minimum what thunderbird provides. all thunderbird contacts should be saved as crm contacts by default, (or vice versa) so no duplicating the contacts entries.

i am willing to devote time to plan the features wish list, & do the beta testing, whenever required. anybody interested ?
