The way we get CPLEX licenses is we apply for academic research license
grants annually.  My last license was for CPLEX 10, and it expired a
couple months ago.  I need to apply for an update to get back to work on
this.

The answer to the original question is that I think it got a pretty good
workout with version 9, which didn't have any discernible API difference
from version 8.  I am planning to give OSI some TLC (including bringing
OsiCpx in line with CPLEX 11) this summer, but I won't be able to start
until July.
