I don’t have any information to support your arguement but I completely agree. HP has been pretty non-comittal when it comes to its proprietary technology: PA RISC, HPUX. I totally see a future of two UNIX variants. Solaris and Linux. This may take a few year to play out so your app may be grandfathered by then. (BTW: I’m DBA in a pure HPUX shop and I am pushing mgmnt to start moving some eggs to the Linux basket).
