remote integration
I don't know if this was part of BeOS in the past, but I would really like to see the abililty to explore remote sites - ftp, ssh, maybe even cvs and subversion - built in. I suppose the best place would be the Tracker?
For example, if you type sftp://domain.tld in a MacOS Finder window, you'll be able to authenticate and browse the remote server as if it was stored locally.
Cheers,
togs

Re: remote integration
Best place is at filesystem level, and already exists for a number of protocols:
1. SAMBA - built into the OS in BeOS R5. Unreliable as hell, but it does work for a while. cifsmount at the terminal, or the buggy World O'Networking demo app that acts like the Windows Networking browser.
2. FTP - http://bebits.com/app/3511 FTP-FS. Mounts an FTP drive as a hard drive, read/write allowed
3. NFS - rather old and probably not working very well anymore, but http://bebits.com/app/1021 allows you to mount an NFS drive as a hard drive
All of these allow -all- apps to treat them like a HDD mount rather than anything else. Its the ideal abstraction layer.
don't forget DAV
A dav fs add-on would rock, as would SVN as it could handle BFS attributes...
Re: don't forget DAV
Yes WebDAV would be a great addition as it supports queries. Both server and client.
