Regarding PlayerPrefs vrs. (WebPlayer && Standalone) Builds

The data that I stored in PlayerPrefs works as it should when testing multiple Web Player instances and on two different PC's when built as a Standalone. However, the data conflicts if I test a PC or MacStandalone build on the same pc.

Therefore, if the logic is that each Web Player instance acts as a different pc, how would one make it think that I am on a different PC (When Building as a Standalone)? A possible solution: running it in a different path?

Regarding to the reference the data should be stored in different directories for webplayers and standalones on Win and OSX. Maybe one of the preference files exceeded the 1 megabyte limit?
