I couldn't agree more!

I'm glad we switched to RTEMS. These issues are history...
In about 4-5 (wo)man-months a BSP can be developed (includes
'learning by doing' RTEMS training). If several projects/labs
could decide on sharing BPSs, money could be saved. Plus,
you have control over the source code.

Unfortunately, WRS

still does not have a two tier licensing scheme for users of Tornado GUI

tool verses folks that are just building and installing executables with

scripts (i.e. typical EPICS application developers). It occurs to me that

there is a potential to significantly reduce the cost of Tornado
ownership

at EPICS installations. It seems that if someone were to modify the SNL

compiler so that it produced byte code which is interpreted at run time

(similar to JAVA) and there was an option to create an alternative IOC

configuration where dependence on the target symbol table by vxWorks

compiled iocCore was removed (we already have this working on other OS
with

R3.14), then the application developer wouldn't need to use a Tornado
seat.

Sites might need to buy Tornado seats for building EPICS base and for

developing drivers, but not for developing EPICS function block
databases or

to develop SNL based logic.

I was just curious if there was any general level of interest in that

approach?

P.S.

I just heard that there is a new 8k US $ per year per seat licensing
model

from WRS which allows unlimited use of any hostArch / targetArch /
project

permutation by one user.
