Flag to pass in /path/to/keystore?

[floating]

I'm interested in a --keystore flag that takes a path to a /keystore directory not relative to the datadir. I'd like to put my /keystore on a removable encrypted drive while still being able to mount and quickly do account operations with geth --keystore /path/to/mounted/keystore. Thoughts? Does a better pattern already exist for this?

I would like to have this, too.

Seems like @kobigurk was nice enough to submit a PR for this. @floating you can try out the PR until it gets reviewed / merged.

I just tried it and it seems to be working perfectly, thanks!
