I really should have explained that better. The old vSigX, just has a path to the sigdb file. My new version would store that sigdb internally (in the app’s sandbox) after acquiring it from the machine or otherwise loading it. You’d still be able to switch actually.
It would be cool if the app on startup detected whether it already has a sigdb for the connected machine, downloading it if necessary, so the user never even has to worry about it.
