I won't comment on comparability to VMS, but UNIX System V Release 4
has dynamically linked shared libraries.  A good place to find
information about the facility, and how it ties into the Elf
object format is the SVR4 Generic ABI, available from Prentice-Hall.
Any of the processor supplements will explain some of the architecture
dependant details for various platforms.
