1-SharePoint Items (Documents, Tasks, and Events etc.) :
Can be acheived using OOB MOSS Search, content sources, custom scopes & managed properties will do the job and more...
2- SalesForce Items (Chatter Discussions, Documents etc.) :
I Don't know a lot about SaleForce; but in general; there is a bunch of options to search external sources outside SharePoint like Federal search, BDC, etc...
3-Exchange Mailboxes Items (Emails, attachments etc.)
This can be achieved using 2 different approches:
i-Add a content source "http:///exchange/" or "http:///exchange/user_alias", but please be aware that users will only get serch results from their mailboxes, except for exchange admins will be able to get results from any mailbox
ii-There is some third party connectors that provide more features for this like the BA Insight exchange mail box connector for shsrepoint; I haven't try it before; but give the trial version a try & et's see !!
4- Network Shared Folder items
This can be achieved using OOB SharePoint search
-Regarding merging search results from all sources in one view while using icons for highlighting the origin; this can be achieved using the SharePoint search object model
-For complex queries & scenarios; I believe FAST (comes with the SharePoint 2010) will do the job.
