Oh my. Sounds like you want it all. Last things first: licenses come
in three flavors:
1. fixed with a hardware dongle
2. fixed without a hardware dongle
if you have either of the first two, you can bring your license with you
anywhere, but noone else can use it. If you have #1 you have to
remember your dongle. If you have #2 you have to have your ethernet
card plugged in at all times (not required to connect to the network
though). With #1 you can even just carry the dongle with you and plug
it into various computers. If you have #3, and are connected to the
network, and your site license allows it, you can check out a license
The best IDL platform is one which allows you to get your work done.
Even though I have devoted some effort to measuring the relative
performance of IDL platforms, the real truth of the matter is, if you
have some operation which needs to run very fast, you really should just
write it in C (or fortran, or assembly, or...), and link it with IDL.
So, with the speed issue cleverly side-stepped, you should probably just
choose the platform you'd be most comfortable on.
IDL will be carbonized, or, more likely, Cocoa-ized, but they have not
said when. Apple has their hooks into RSI, so I'd suspect something by
Macworld NY in July (wild speculation). As to optimized speed on a G4
with Altivec, only time will tell.
