I was wondering whether android/GN2 is a viable platform for my needs. Can android users please respond to the following questions:

1. Does android have a openvpn client for routing everything over the remote server?
2. Does android/GN2 have native sip support?
3. Can the sip clients use openvpn as well?
4. Is there a good irc client something like xchat on N900? How is the usability with on screen keyboard.
5. Can it play streaming ogg music (i have my own icecast server)
6. Does it have an openssh server.

Ok, i finally bought GN2 and here are my answers to the questions above:

1. On the play store there is an openvpn client and works quite well even on non-rooted phone. However, only 'tun' interface is supported.
2. There is a very poor 'native' sip support in the dialer. However, there is an application call Csipsimple which is awesome and even supports SRTP/ZRTP. Sip calls are choppiness free unlike N900 (see my signature below).
3. Yes, CSipsimple routes the calls over openvpn.
4. There are some irc clients available, but not as good as xchat. The onscreen keyboard is no match to N900's hardware keyboard. There is a usable keyboard called 'Hackers Keyboard' on google play which provides the full keyboard.
5. This is pathetic on Android. The standard media player cannot even play network streams!. There is a paid application on google play store called xiialive which can play custom icecast urls.
6. Dropbear is available on a rooted device. There is busybox as well available. But out of the box the shell is very poor.
