Everything that needs more than a single process won't run, either because it needs a system service or because it does multi-process-sandboxing. Single-address-space is extremely limiting for a lot of stuff, so most webservers are out. Not sure if threads would even work. Any desktop software is out anyways. Basically you will have to write your own software for this model of operation, or pick stuff that is accidentially suited, which won't be a lot.
