This is getting off track but I have a question for those savvy computer people that are reading this (hopefully). I'm familiar with tools such as Exceed/Reflection on windows which allow access to Unix type systems (Linux, Solaris/Sun).

Can you set up the Mac Mini (or any Apple computer that you leave on) in a manner where you can access it via any computer anywhere?

I guess "access" would fall into a couple of categories:
1. Access files
2. Run applications on the Apple system

Any good web sources on doing things such as the above?

I have a technical background but my experience with Apple products is more limited and my work hasn't been in IT or network infrastructure (other than some classes).

I'm guessing the biggest concern is security since if you let in one person there is always a chance someone else may find a way into the system.

Thanks
Rich
