Possibilities for commercial software?

[Ortwin Regel]

I like open source and stuff but some things, especially games, are
closed in many cases. What are the possibilities for selling closed
software for OpenMoko devices? Will there be a central online
marketplace? What about DRM, is there a way to bind a program to a
sync ID like it's usually done with PalmOS or to a device ID? (It
should be possible to bind it to an SD card ID, right?) Any creative
ideas how to solve the usual issues people have with stupid DRM
systems etc. and still being able to get money for software
development?
