I lost track of who was speaking for each part here, but no matter:
I can manage to do the switch to Linux. But I would not want it for my 
everyday work. Do you think it is possible to use the Opteron/Linux 
system as a remote server and submit jobs to it from Stata on another 
computer (My Mac, and My colleagues Macs and PCs)? Or is it only 
available from the command line?
I think it is possible to use the Linux box as a remote server and submit 
Stata jobs to it; but you would need to ascertain that with someone who 
knows more about setting that up than I do.  In fact, Stata tech support 
probably could tell you.
I typically do this.
I use putty to establish an ssh connection to the server from my winXP box, 
and then I usually run stata for linux (suse9, dual opteron) in console mode.
If I want to use the stata gui I just make sure cygwin has started locally 
and the xserver for cygwin has also started.  Then starting xstata on the 
server brings up the windows for viewing graphs, etc.
The sharpness of the graphics is reduced compared to running stata directly 
on the windows box, but I believe that is the fault of the cygwin xwindows 
server, rather than stata.
the only complaint I have is I cannot -graph use- .gph files that are on 
the server when I am running stata locally.  Nor does double clicking on 
them in my network neighborhood work.  I have to copy them over to the 
local hard disk.  Other programs (Excel, etc) on the local winXP box can 
access files on the server directly (via samba).
