Yes, floating network licenses *can* be used across different
architectures. We have three floating licenses that are used across several
Suns, two RS/6000s and an SGI. If you take a look at the idl executable
itself, you will see that it is actually a shell script that figures out
what architecture you are on, and then starts the correct binary.
Thus, our IDL directory has a generic bin directory, as well as bin.ibm,
bin.sgi, and bin.sunos.4.1.sun4 (all as named by RSI, not us). In our
case, all of this is on a "/usr1" partition that is NFS-mounted from a
server to all appropriate machines (even across architecture boundaries).
In addition to these floating licenses, we also have a node-locked license.
The advantage of this setup, we figured, is that users can access IDL
_from their local workstation_, and are only forced to go to the server (and
setenv DISPLAY, etc) when the three licenses are in use by others. And
since the server license is not limited, as many users as the server can
support can use it.
We have had the one fixed license for many years, but it sounds like our
current setup is much like what RSI is suggesting to John Kemp. There are,
of course, other ways to do it, but it works for us.
Hope this helps.
