No ...
You get an email, it has a save attached. You save the file to two different locations. One you play with, the other you open in the editor and screw with. Pretty simple stuff.
It would have the same effect as me posting your game password ... once I did, would you want to continue to play a PBEM game knowing the other player can now see all your moves?
Data is data is data ... once you have access to it, it can not be taken away.
Seems as if the "fix" for this wouldn't be that hard. To edit something "in Game" would just have to require both players input. Any time one player "opened" the DB, it would send a "flag" to the other.
If you've both discussed a "problem" that needs dealing with, you both input the same "fix". And if you get a turn with a "flag" and no mention of a problem from your opponant..., you will know you are dealing with a "scumbag" and can take the appropriate measures.
For those who assume that everyone will look over their opponants OB and dispositions while the Editor is opened, they can balance the need to "fix" a problem with the knowledge that BOTH players will have an opportunity to check the other's database. As long as both sides get the same opportunity/suffer the same loss of security, it's not really unfair. And it will make sure that only important problems are "fixed on the spot".
