Not only suggested, but actually implemented in VM SSI (back in the VM/SP days). The SWITCH command would move a virtual machine within a SSI cluster of machines. It took an immense number of CP mods to make this work. Perry Ruiter and I took a look at this again in 2000, and pretty much concluded that it would be unmaintainable to try to do this level of modification again. Things have changed too much in CP to reuse the old code, and the sysprog skills to implement it just don't exist any more. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
