It struck me when someone asked about doing DTP on the IT, that I haven't yet come across a vector drawing app for the N800. There was Dia for the 770, but AFAIK it hasn't been forward-ported.

Would something like the venerable Xfig (http://xfig.org/) be portable to maemo? It's pretty stable and generic enough that it could serve as a drawing package, CAD thingie and even a simple DTP proggie.
