I should be able to exercise my right to defend myself in any state of the Union.
As Tom said, driver's licenses are a 'privilege' CCW is a right.
State boundaries should not apply once qualified to CCW.
You can use the DL system as a 'guide' though:
1. You must be issued the CCW license in the STATE that you LIVE in.
2. Once issued, you may legally CCW in ANY state, as long as you adhere to that states rules.
3. The Federal gubmint will be involved in order to insure said reciprocity between states.
All that being said, just go back to the 1800's with national open carry.
