Missing Apps

I’m just wondering what the thoughts on missing apps for RISC OS.
My slant is towards networking based applications, on my list to do in the current order:

BBC News
RSS Reader
Jabber Client
Twitter Application
Facebook Application
OpenVPN Client
Terminal application (lovely looking one, I really like Terminology – I’ll look at what I can do with Nettle first when I get round to this)
Groupware Client (aka evolution or outlook)

I’m just interested in what other network based applications are missing from RISC OS.
I really hate using all other desktop OSes and phone OSes too. So I’d really like to write applications that cause me to use them so I can stop using them.

I figure there would be more interest in RISC OS if people didn’t have to switch to other OS’es to do basic work.
Feedback from other people would be great, as I’m happy to change the order of the stuff if I like the ideas – and if I don’t someone else may pick it up ;-)

I would sometimes find a VNC server useful. There are plenty of VNC clients already, but although there is a VNC server I have tended to find it crashes a lot. Not tried it for a while so it may be improved now.

An IMAP-based e-mail client which doesn’t store e-mails locally (so different to the Messenger approach) would be nice, and more generally than something devoted to Outlook. I have to admit though, the main reason I use Outlook webmail on the Linux box is to check my work diary, and doing that from RISC OS would be nice.

I find Nettle to be very good for terminal stuff, except for the problem of up-arrow not working in a Linux shell session. I’ve never got to the bottom of that.
