holy cow.  i'm cc'ing this out to a number of lists i know of in
case someone can answer authoritatively.

does anyone else know how this could be done?

is it possible to get memory allocated in one process to be shared
with another process *at the same address* on unix, os/2, nt, vms etc?

the critical one for the dcom project at the moment is unix.

please could you cc in the dcom-dev@lists.dcerpc.net list
in any discussions, for relevant records.

thanks for your help,
