I've been using snx as my goto app for doing some real work when I only have my trusty n800 and bluetooth keyboard with me. Now that it has stopped snowing I've been biking more to work and ditched my heavier laptop for the commute I have been using snx more and more but suffering somewhat without persistence of applications (tough to edit a document only to loose connection and have it close itself).

VNC is ok but a does not incorporate the protocols that allow NX and snx to work well over slow connections (like my 3G). I've tried using snx to run a vnc viewer pointed locally at the remote server - which actually works pretty well but seems overly complicated.

I tried x2go - which is great on a pc and there is a little known client for maemo. The maemo client is ok but has some bugs that make it unsuitable (and it looks like there is not further development for maemo) .

Lastly I been playing with xpra mainly via CLI but they have a nice GUI too.

I know there was some thought of making snx apps persistent, but would it be worthwhile to look at porting xpra? Just a thought from a non programmer.
