Aside from all the issues that plague bitcoin, what would be a more secure way of 'touching' the wallet.dat file?
Keep in mind that:
1) IO is expensive
2) the file will not be encrypted
3) the file will/should not be hosted on the same machine
4) the file will be accessed in excess of 1,000,000 times a day; maybe more.
The only thing I can think to do is do all the transactions with imaginary bitcoins until the end of the day then, at night, push all the transfers; almost like banks do.
