It is my understanding that the things that will run on VM/XA SP2.1 will run
on VM/ESA 1.0 (w/ESA feature) but will NOT run on ESA1.1.  VMSecure 4.4a is
a prime example.

If this is true, what are the differences in ESA1.0 and ESA1.1 that prevents,
for instance VMSecure 4.4a, from running under ESA1.1?  Is it merely the case
of VMSecure 4.4a checking for ESA1.1 and stopping if you are on ESA1.1?

If you make the assumption that the old products COULD run on ESA1.1, then I
think it is reasonable to infer that the old products are probably checking
for ESA1.1 via the diag x'00 output (program product bit map) and exiting
if the ESA1.1 bit is set.  If this is true then there is probably no
technical reason why you can't NOP this test and carry on with business as
usual.  I suspect that there may be legal reasons for not doing this.  I also
suspect that you wouldn't get much support from SCI when the thing broke...

The standard party line I get from SCI is 'The VMxxxxxx/E products run faster
and jump higher that the old products.'  They don't seem to be listening when
I tell them that we are perfectly happy with the performance of the old things
under VM/XA SP2.1.

Any comments?
