Glad to see you still interested :p
Remember that a single man is not sufficient, so any help is appreciated :p

Here is what needs to be done :
- namecoin bundle : easy support for .bit (mini GUI/systray to show nmc-control status [python ?] + proxy with nmc-control [python] + namecoind integrated)
- namecoin rules update : bigger records, revised fees
- bitcoin rebase : use latest bitcoin code, or another lib
- some GUIs to register domains, id, etc
