| Fully implement the 5250 protocol | Partially complete. Complete support for the enhanced 5250 protocol needs to be added to lib5250. |
| Lightweight | So far pretty good. On my Slackware 10.1 system with gcc version 3.3.4 x5250 weighs in at about 676 kilobytes. |
| High performance | Pretty good. The small delay in start up is due to lib5250 connecting to the remote host, rather than x5250 taking CPU time to start. Overall, it responds as fast as xterm does. |
