AppleShare IP 5.0 works differently with multi-launch applications. AppleShare 4.x servers would let the server administrator set from one to 250 concurrent launches for any application, whether it supported multiple launches or not.
The Finder supports a file flag called "isShared" which reports if a program is designed to be launched by multiple simultaneous users. AppleShare IP Admin now looks at that field, and enforces its setting. To summarize:
AppleShare 4.x- isShared Finder bit is ignored
- AppleShare Admin lets up to 250 concurrent launches (250 is the default)
- Concurrent launches are restricted to the number set in this AppleShare Admin panel
AppleShare IP 5.0- isShared Finder bit is used to determine "configurability" of concurrent launches
- If bit is clear, AppleShare IP Admin cannot configure concurrent launches, only one launch is allowed
- If bit is set, AppleShare IP Admin can allow up to 250 concurrent launches
