OK. Entrepreneurs, read up. I’m gonna give you some ideas that’ll make you rich.

Start my ranting:

1. Can I really be the only person who wants to share Thunderbird/Seamonkey address books with a spouse? I mean, how hard can it be?

What I’d like:

• Each of our “Personal Address Book” collections show up as a list on one another’s address books as a list (e.g., mine shows up on my wife’s machine as “Samuel’s Address Book”. It could use the machine name instead, if it’s easier).
• We can see one another’s mailing lists in our address books
• Manual sync is fine — automatic would be even better
• Simplistic merging is OK, so long as there’s a way to resolve conflicts
• Ability to mark lists as private or shared

2. Can I really be the only person who wants to share a checkbook program with a spouse? I mean, how hard can it be?

What I’d like:

• Ability to enter checks / charges / deposits into a common account register
• Ability for either person to perform reconciliation
• Ability to have accounts that are not shared

3. Can I really be the only person who wants to have an intelligent, revision-capable backup script that doesn’t require shell on the destination end? I mean, how hard can it be?

What I’d like:

• rdiff-backup, only permitting an ftp-based push of the backup file.

More to come, as I experience more outrage.
