Our
Briefcase app mixed with
WebDAV (some notes recently added to that wiki for windows users) or our
DnD plugin (for which we do have cross-browser/platform
plans) is awesome, but some out there might have smaller quotas, don't have their own
NAS, or other setup for anywhere access (too many methods to list). And some of those auto-sync solutions are just handy.
So Zimbra gear to the first Zimlet for interaction with one of the major storage sites out there.
Some ideas:
-Adding files a-la
Flickr/Snapfish Zimlet style as email attachments.
-Dragging messages to the Zimlet would upload any attachments contained within to your storage site.
-Heck even dragging from briefcase folder to the Zimlet.
Dropbox Syncplicity Amazon S3 (if you beat
Bug 4693 - Mount S3 bucket as Briefcase item & actually many of those sites use that for a backend)
Yahoo! Briefcase Box.net The Linkup Xdrive Avvenu Jungle Disk
Could list these for days, so you're obviously welcome to suggest other services to mash-up with, as there's tons of these out there. We don't discriminate so even
Foldershare - but obviously some (ok most) don't have easy APIs or even open APIs at all

so I imagine some serious examination of their communication methods will be in-order.

Should there be some kinda 'flood' of submissions, preference goes to those that have at least some sort of perpetual free storage & the bigger the 'max file upload size' the better. ie:
Amazon's S3 or
SugarSync's 45day free accounts loose to
Syncplicity's unlimited free storage (
for now) or
Dropbox's 2 gig, or whatever's 5gig etc.)
(Of course being a Zimlet, admins can obviously choose to not install because of offsite security concerns, personal/work mix issues, or ISP's who price by mailbox quota - so let's not circle the drain on those reasons if you're asking 'why this contest?' - it's for endusers.)
No end date (till this post becomes several years old - then ask) as I did say first person to make one, but you can always impress us anytime and we might just cave!
Not the Zimlet Dev type? You can still suggest your favorite service below.
Yes there's
Bug 22080 - Access SMB shares via Briefcase - but again, not everyone can offer unlimited quotas.
