Is sandboxing on OS X already state of the art?

[Tiemo Hollmann TB]

Hello,

joining Vaughns question to sandboxing I also didn't cared about sandboxing
up to now and I am not good in handling Mac techs specifics.

Because I am just preparing a new version of one of my programs, where I
have to change some file paths anyway I would be happy, if somebody could
give me some opinions on sandboxing.

Is sandboxing already "state of the art" for Mac applications, which are not
sold from the Mac app store? As I read Richards post, it is not yet. But do
you think, sandboxed apps and / or the distribution path over the Mac app
store are going to be obligatory in near future, so that it would be wise to
sandbox my app already now, to not make again bigger changes on my program
in one or two years again? Or do you think the "classic" programs may exist
parallel to sandboxed apps for years?

I would be happy if I just could go on with my "old style" program and not
having to care about xCode, sandboxes, manifestes, appstore, etc.

Any statements welcome, I am a little lost, when reading the Apple
guidelines to sandboxing
