As this seems to have turned off topic I think I will join.
I am in the process of setting up my own business running on OSX. This is going to be quite peculiar as what we do is not very usual (analytical marketing lets say) but I will be working a lot with databases (ProgreSQL), statistical packages (R) and integration with office using applescript (frist) and Ruby/Python (later).
My needs also include good security (two factor , ssl and LDAP...) i have researched the topics quite well and I am starting to deploy the solution using a prototype machine.
More traditional staff is running the typical back end services (including (S)FTP, WebDAV, AFP server, and subversion and Alfresco server eventually)
So the net result for you guys is that I may be able to help with some "esoteric" issues on Mac.
I recetnly compiled Apache 2.0 on tiger, it took me some time to figure out but I would like to encourage people to start looking at the mac as a truly capable enterprise platform... or better nto as this is one of my key competitive advantages
Feel free to post a line, I look forward to meeting you at your server room
