Lotus for sysV (multi-user?)

Lotus is advertising a system V version. I called and was told that
it's available now; list prices around $950 single-user,
and $1100 for up to 10 users. A clear example of pricing
to reflect "value" rather than cost; but how do you suppose
they limit the number of simultaneous users?
1) do it in the code itself: very difficult with shared text and
virtual memory
2) create lock files. Hackable by wrapping lotus in a shell that does
chroot
3) look at process table. Hackable by linking new names, or renaming lotus;
but of course lotus could prevent renaming itself by looking at argv[0]
Anybody know of another way?
